Potential North-South & County Light Rail Line Should Include ‘Green Track’

June 30, 2022 Environment, Featured, North City, Planning & Design, Public Transit, Transportation Comments Off on Potential North-South & County Light Rail Line Should Include ‘Green Track’

No, I don’t want the rails to be painted green. Instead I want the space between the rails to be green with vegetation, where possible.

Why? Aesthetics, cooler temperatures, management of stormwater runoff, etc.

Pre-Katrina you could see natural green track in New Orleans LA, April 2004

Green track isn’t limited to only historic lines, it’s increasingly common in Europe with some limited use in North America.

Over more than 6 (six) decades Green Tracks are popular through out Europe in dense urban areas. They are a fantastic tool to mitigate stormwater issues, to reduce noise and certainly to beautify their integration. Green light rail tracks demonstrate environmental responsibility and they value their customers by making things nice, green and beautiful. Today there are over 500 miles of Green light-rail tracks in Europe.

The living green layers within and around the tracks reduces the noiseand absorbs stormwater. Thus, reducing combined sewer overflow. Modern track systems are typically Ballastless Tracks or Slab Track systems. Basically, a traditional elastic combination of ties/sleepers and ballast is replaced by a rigid construction of concrete or asphalt. Because such systems are ideal for greenery, it is even possible to create additional stormwater retention and detention from surrounding impervious areas with the system.

Already, in 1995 Green Roof Technology filed patents for greening systems on Ballastless Track systems. Currently there are around 300 miles of green tracks in Germany alone. As a result, these tracks eliminate at least 150,000 gallons of water per years from entering the combined sewer system.

In North America, Baltimore started with some experimental Green Light-rail Tracks in 2011 insisting on Sedum mats. The testing was less promising because Sedum mono-cultures are not a good choice for most green light-rail track system. Unfortunately the advice from Green Roof Technology using a smart mixtures of grasses, herbs and wildflowers was not heard. Some call it learning by doing – well – they just don’t do it. (Green Roof Technology).

Typically rails are supported by ballasts, treated wood or concrete pieces set into the ground perpendicular to the rail. Our original 1993 light rail line used wood ballast, the 2006 Shrewsbury extension (aka Blue) line was constructed with longer-lasting concrete ballasts.

Our current lines are Red & Blue so naturally I’d like this new line to be the Green Line. Green track for the Green Line!

It can’t be everywhere, but in many places it can be. A lot of the new line would be in the center of Natural Bridge, which recently went through a quick traffic calming project that reduced vehicle travel lanes to one per direction. Adjacent to Fairgrounds Park the center is green — would be greener if not on top of asphalt.

Looking east toward Grand
Looking west from the same location.

I think the green looks nice, helps keep the area slightly cooler.

While we’re on the subject of alternatives to impervious concrete, another would be water — yes, wet track! Rail going through a fountain…

Not sure if or where this might work, but I think it’s very interesting. Perhaps on Jefferson near the stop near Olive or Market? Guests in new hotels could look down from their rooms and see transit & water converge.

I’d just like us to consider something other than boring ordinary impervious paving.

North-South MetroLink Study Update Looking To Stay On Jefferson Avenue, Avoid Previously Planned Circuitous Route

June 16, 2022 Environment, Featured, Planning & Design, Public Transit, Transportation Comments Off on North-South MetroLink Study Update Looking To Stay On Jefferson Avenue, Avoid Previously Planned Circuitous Route

The idea of a North-South MetroLink light rail line has been discussed for many years — too many. We’ve had a couple of studies and locally preferred alternatives over the 15+ year period. Currently Metro is looking at the most recent and “tweaking” it to make it work financially with the city funds from our transit tax. So when I heard this would be included in the Citizens for Modern Transit (CMT) June “Talking Transit” online event I immediately registered. It took place a week ago, but it’s online — link in a moment.

The last alternative was eastbound on Natural Bridge, coming south on Parnell/Jefferson to Cass (to include the large NGA workforce), east to 14th, eventually to 10th, back over to 14th, west on Chouteau, south on Jefferson.

2018 detail map showing the North-South MetroLink in orange. This is no longer possible because of the convention center expansion project closing 9th street.

So basically on Jefferson north of Cass and south of Chouteau, but taking a highly circuitous detour to go through downtown — and briefly east of Tucker.  The distance between those two points on Jefferson is 1.6 miles — in basically a straight line that would require no left or right turns.m

In a 2006 post I suggested a modern tram route on Jefferson, with a new MetroLink station where Jefferson crosses over the existing light rail line, so riders could transfer between lines. Well 16 years later they’re looking at doing basically just that — run in-street light rail on Jefferson with the addition of a MetroLink station at Jefferson. This was disclosed by Bi-State Development President & CEO Taulby Roach at 3:23 in CMT’s event a week ago (watch 0n YouTube).

Bi-State graphic, the orange-yellow mostly vertical line in the center shows the initial phase being evaluated now.  The pink sections are “areas of persistent poverty.”

 

With the NGA, Centene Stadium (MLS) and planned new hotels (Jefferson & Market) this a hot corridor.

The rail wouldn’t be a tram in mixed traffic, it would be in a separate dedicated center section, still low-floor though. The vehicles for both are nearly identical. In-street light rail vs tram basically means dedicated right-of-way and fewer stops, to improve overall speed.

Obviously I’ve long thought a stop at Jefferson on the original MetroLink was a good idea — the distance between the Union Station & Grand stations is just so excessive. I often talk about focusing on corridors, not circuitous routes, and Jefferson is an obvious corridor for a transit project.  It’s not a perfectly straight line, but it would eliminate a huge amount of turns.

Like previous North-South studies, the idea of going out west on Natural Bridge allows a future phase to connect into North County. This could help get county residents to employment opportunities at NGA, and in Downtown West/Midtown.

The study update is looking at the latest low-floor vehicles to use. Because of some tight points they’re looking at vehicles that could run for short distances on battery, with the usual catenary most of the distance. This is called off-wire. An example is the Brookville Liberty, in use in cities like Dallas, Milwaukee, and Oklahoma City.  I have no idea which specific vehicles Metro is considering, but the technology to go without a catenary for a short distance is proven.

I’d hoped to have visited Oklahoma City by now and ride their Brookville Liberty vehicles., but rental cars & flights have just been too expensive. Again, I’m not sure what vehicles Metro is considering, this is the only off-grid vehicle I’ve ever ridden before.

In the CMT event on Zoom Taulby Roach indicated they’re planning on closed platforms  — having to pass through a fare gate to reach the platform.  This coincides with Metro’s platform project to install fare gates at all MetroLink stations in Missouri & Illinois.

Hopefully Metro’s latest look at North-South rail will result in actual construction, eventual operations.

MetroLink Escalators “Temporarily Closed” For Years

April 18, 2022 Accessibility, Downtown, Featured, Public Transit, Transportation Comments Off on MetroLink Escalators “Temporarily Closed” For Years

Escalators are great, very helpful to those who find stairs difficult.  However, like elevators, they’re expensive to install and maintain. Escalators exposed to the elements are even more challenging to keep in operation.

When our original light rail line opened in 1993 two stations were located within an old freight tunnel under the central business district (CBD). The Convention Center and 8th & Pine stations were designed with stairs, elevators, and escalators. Because the tunnel is narrow the tracks are in the center, the passenger platforms are on both sides — one per direction of travel, east or west. This meant a total of four elevators and four pairs of escalators — all exposed to elements to a degree.

When the Shrewsbury (Blue) expansion line opened in 2006 its three underground stations had stairs, elevators/ramps — no escalators.

In 2018 & 2019 I’d frequently see ThyssenKrupp maintenance people working on the Convention Center escalators, or at least their service truck on the public sidewalk near the westbound entrance/exit. April 1, 2019
Here’s the same location on November 2, 2020

I search all Metro press releases from 2019 through the present, only one mentioned escalators in the subject/summary.

From May 3, 2021:

Rehabilitation work on the westbound escalator at the 8th & Pine MetroLink Station in downtown St. Louis begins on Tuesday, May 4. During this project, the station’s westbound elevator will remain in service, however, the accessible pathway to the westbound side of the 8th & Pine Station (near Pine Street) will have to be closed temporarily.

MetroLink riders who are traveling to or from the 8th & Pine Station and use a wheelchair or mobility device may need to make adjustments to their commute, as it will be necessary for riders to use stairs (located near Chestnut Street) when entering or departing the westbound side of the 8th & Pine Station.

The escalator rehabilitation work is expected to take approximately three months to complete. (Source: Metro)

The above press release was issued a week after I followed up with Metro again since I hadn’t received any specifics from my inquiry on December 28, 2020. Receipt of my original inquiry was acknowledged but I never received anything. Just the one press release, above.

Since I use my power wheelchair when using transit why do I care if the escalators aren’t working?

Well, it looks bad to have something temporarily non-functional for days, weeks, months..years.

What do I hope to accomplish with this post?  I want all the escalators either in good working condition — or I want them removed and replaced with fixed stairs (I can’t speak to concerns of those who have a hard time with stairs). It obviously won’t happen quickly, but steady progress needs to be demonstrated.

It looks very bad for visitors to see out of service signs, but it’s even worse when returning visitors say “oh yeah they were out the last two years I’ve visited.”

Amtrak Faster to Chicago than closer Kansas City

January 31, 2022 Featured, Public Transit, Transportation, Travel Comments Off on Amtrak Faster to Chicago than closer Kansas City
The Texas Eagle train uses 2-level trains like this one, the Lincoln Service to/from Chicago uses a one level train.

In October 2021 I booked an Amtrak trip to Chicago for a weekend next month. At that time the trip was scheduled to take 5 hours 40 minutes to Chicago Union Station, via Lincoln Service.  This is faster than it has been over the years — improving every year since the American Recovery and Reinvestment Act of 2009 was signed by president Obama. Amtrak recently revised my trip — it’ll now take only 5 hours 25 minutes. Fifteen minutes quicker than before!

Amtrak will implement a schedule change for Chicago to St. Louis Lincoln Service and Texas Eagle trains, effective December 13.

These schedules reflect a maximum authorized speed of 90 mph for Trains 300 – 307 and Trains 21 & 22. Chicago to St. Louis corridor travel times are reduced by approximately 15 minutes, end-to-end.

Updated schedules now on Amtrak.com reflect these changes, as do new bookings, eTickets and other boarding documents.

This is a step toward 110 mph schedules that are planned for the next 12 to 18 months. These improvements use federal grants and other funds from the Illinois Department of Transportation. (Amtrak)

These speeds aren’t close to high-speed rail experienced in other parts of the world, but it is very welcomed.

Driving a car is still faster, but it’s exhausting and very expensive to park in Chicago, station to station is 297 miles, requiring 4 hours 20 minutes. Of course, that’s assuming no restroom/eating/stretch breaks.

Kansas City is closer to St. Louis than Chicago is, so you’d think both driving & train travel would be less. Driving is 250 miles — 47 miles less than to Chicago, requiring 3 hours 37 minutes. Makes sense. The train trip to Chicago, however, is 5 hours 40 minutes.

Yes, the trips used to take the same amount of time even though one is closer. Now the STL to CHI train is faster. Once more improvements and speeds of 110 mph are achieved the time difference of traveling to Chicago compared to Kansas City will be even greater.

It would be nice to see similar improvements made to better connect St. Louis and Kansas City, spanning the width of the state.

Decisions Applicable To Bus Rapid Transit And Local Bus Service

January 27, 2022 Featured, Planning & Design, Public Transit, Transportation Comments Off on Decisions Applicable To Bus Rapid Transit And Local Bus Service

Monday’s post Bus Rapid Transit (BRT) Not Right For St. Louis certainly ruffled a few feathers — at least among non-transit riding civic boosters. Lots of good discussion on the Facebook post.  What we need next is to go through specifics one by one to see if there is any consensus. BRT has been implemented worldwide with great success. In general, BRT projects in the United States have been less robust than in other countries. That’s ok.

The Healthline in Cleveland, 2015. Click image to see my 4th post on Cleveland’s Healthline from November 2015.

My previous post was simply saying we can’t have a gold-level bus rapid transit system, per the Institute for Transportation & Development Policy (ITDP) Scorecard. To date no BRT system in the USA has achieved a top gold rating. The ITDP has ranked 10 BRT lines in the US with the following results:

  • Three (3) Basic
  • Five (5) Bronze
  • Two (2) Silver (Cleveland’s Healthline = 76, Hartford’s CTFasktrak Busway = 79.2)
  • Zero (0) Gold

Countless others being marketed as BRT don’t even qualify for a “basic” designation. Ouch. I guess as long as the users are pleased with the line compared to a conventional local bus then it doesn’t really matter what it’s called. Interestingly none of the 10 in the US have BRT as part of their name.  Our light rail system has two lines: Red & Blue.

Two battery electric 60 foot articulated buses recharging in November 2021. The right bus just arrived, the left bus is about to leave. Note that these buses have a unique color scheme to separate them from regular local buses.

Perhaps we come up with some criteria to use for calling a very high frequency bus route by a color name rather than the legacy bus number. For example, our busiest bus route (#70 Grand) could be the Green Line. Maybe if we made big changes to the #95 Kingshighway bus route it becomes the Orange Line?  And so on. Then we wouldn’t need to quibble over the BRT term.

Where I think we can agree is our next big transit investment in the city will have rubber-tired transit vehicles, not rails. How St. Louis County invests their transit dollars is a separate issue, they might opt for light rail in a street and/or an extension south from the Shrewsbury station. Today’s post is focused on the city, though applicable if the county considers a BRT-esque bus project.

Beyond the marketing name & tires there are many other items to be considered:

  1. Type of propulsion (diesel, hybrid, compressed natural gas (CNG), fuel cell electric, battery electric, overhead cable electric (commonly known as a trolleybus)
  2. Fare collection (on-board, off-board, honor, no fares)
  3. Boarding (curb height or raised platforms for level boarding; front door only or all doors)
  4. Stop intervals (2 blocks, 1/4 mile, 1/2 mile, more; if more than 2 block local will a local bus also run the route less frequently to serve those unwilling/unable to walk to the farther stops)
  5. Stop locations: center of street, right lane, or a mix of both)

Let’s go through each, discussing pros and cons to consider when making decisions.

#1 Type of Propulsion

In 2022 I  think we should invest only in transit vehicles with zero tailpipe emissions. That would eliminate diesel, hybrid and CNG. The three electric options each have their own pros & cons, infrastructure needs. Battery electric buses, like the 60 foot articulated buses on the 70 are presumably heavier than an electric trolleybus. Overhead wires vs increased wear & tear on streets and sourcing of rare earth metals. Battery electric buses (BEB) need to be quick charged during service, whereas the trolleybus doesn’t need to — but not everyone likes overhead wires.  Some trolleybuses have small batteries to allow them to operate any from overhead wires. Hydrogen fuel cells are another option, not sure if one can go all day without refueling during the day. If so, is that feasible. Fuel cell buses are heavier than trolleybuses but presumably lighter than BEBs.

Metro has historically purchased buses from Gillig, but the new articulated battery electric buses used on Grand came from New Flyer. The latter offers more sizes and propulsion choices.

#2 Fare Collection

This is an important area because it determines how the stops are designed.  First is getting our transit agency caught up on fare technology — assuming we’re going to continue collecting fares from users.

In August 2006 a Metro engineer explained the then-concept of smart fare cards to me.

That was in August 2006, at the opening of the most recent extension of the high-floor light rail. Metro’s Gateway Card finally appeared in spring 2018 — twelve years later. It has been almost four years now and nobody uses it. When I ride the bus or light rail I don’t see others tapping their cards. These cards are available for full fare & senior customers only — I think I’m still the only non-senior reduced-fare user with a Gateway Card.

Metro was working on a website login and app to go with the card, but it seems they’ve abandoned it in favor of a smartphone app to use for fare payment. Millions were spent changing bus fare boxes to allow cards to be tapped, and readers were placed at the entrances to the 38 MetroLink stations so security could see the green light as each person taps their card to enter.  Huge investment of time & money for nothing. People do use the Transit app to buy digital tickets & passes.

I prefer having a reloadable card that calculates if my second tap qualifies as a transfer or new ride. I’ve seen systems that use both smart cards and apps. The goal for all is to not have fare payment holding up boarding, When I visit Chicago locals and the vast majority of visitors use their smart card — boarding is so much faster.

A faster bus route isn’t going to have the driver give those who paid more a daily transfer. Yes, currently every Metro bus in the region gets little pads of transfers to use for that date only. Massive waste of time & money that Metro continues. You’ll often see these as litter around bus stops, especially since most bus stops lack basics like a trash can.

Moving on…

Lets assume everyone has a smart card. By tapping it on a reader at MetroLink station entrances (off-board) or on the bus farebox (on-board) the appropriate fee is deducted from the card balance. If funds are insufficient it gives you a red light & buzzer instead of green.

Since opening in 1993 our light rail has had off-board honor system fare collection. In response to calls for turnstiles it’s going from an open platform to a closed system. If we’re going to build nice new bus stops for a rapid line we need to decide where the user taps their card. Currently bus riders using the smartphone app show the driver their valid ticket upon entering, but that wouldn’t work if boarding is allowed at all 3 doors (60 foot articulated).

Would bus stops for a new rapid bus route have the honor system for accessing the platform & bus? I can’t imagine that would go over well. If we want fare verification performed off-board that means turnstiles.   The current smartphone app isn’t designed for use with turnstiles in mind.

#3 Boarding

Two questions here, both related to #2 above. Platforms level with the bus floor speeds up the boarding process for everyone, whereas curb-level boarding requires passengers to step up into the bus.

In the case of us disabled users (wheelchair, walker, etc) typically a ramp is unfolded to come down to curb level. The BRT scoring is better for smaller horizontal gaps between the platform and the bus floor:

Even corridors that have been designed to accommodate platform-level boarding could have gaps if the buses do not dock properly. A significant gap between the platform and the bus floor undermines the time-savings benefits of platform-level boarding and introduces a significant safety risk for passengers. Such gaps could occur for a variety of reasons, from poor basic design to poor driver training and technical opinion varies on the best way to minimize the gap.  (ITDP)

Some buses designed for BRT use have a bridge that can pop out to close the gap, others the driver has to come set a lightweight bridge in place.

The other aspect of boarding is if everyone enters through the front door only, or all doors. If the decision is made to eliminate fares, have turnstiles to access the platform, or the honor system, then boarding can happen at all doors.

#4 Stop intervals

This is a big one. With my power wheelchair I can go miles without any issues — assuming curb cuts are in place, snow & ice are cleared, etc. But many are used to frequent bus stops, people who use walkers or a cane might struggle if their local bus stop no longer exists. They might already walk a good distance to reach the bus route.  The solution in some cities is to have the BRT bus stop roughly every half mile while also operating a less frequent local bus. By having fewer stops you increase the possibility of having new development occur at these points, assuming zoning is sympathetic to requiring increased density at these spots. Fewer stops requires public & political buy-in to make it successful.

#5 Stop locations

Where the stop is located depends on where the bus operates. If it’s in the center of the right-of-way then obviously you’re going to have center platforms. Keep in mind some systems have a mix — some center, some right. Like our light rail vehicles, BRT vehicles usually have doors on both sides to accommodate different platform locations based on particular conditions. Having center dedicated lanes with center stations, even part of the length of the route, improves performance. If so you’ve got to make sure pedestrians crossing to/from the center are safe from motorists. The nice thing about center platforms is if you want to go the opposite direction from where you are, you only need to cross half the street to get to the stop.

Closing Thoughts

Even if the ITDP doesn’t consider a big transit investment BRT the only two groups that matter are the public and the feds — the ones determining if a project qualifies for matching funds. Other regions are ok with their BRT line not meeting ITDP’s minimum criteria to be considered. It’s up to all of us to participate, listen to others.
