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.

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.

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

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.

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).

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.

Proposed Rail Transit Through Downtown, An Alternative To Delmar

Last week I promised an alternative to the proposed alignment for the proposed northside-southside light rail study. At the time I thought my alternative would work only with the Cass option, but it could work with the North Florissant alignment. First, a look at the overall plan at this point.

Now let’s examine the downtown inset from the upper right.

Now let’s examine the downtown inset from the upper right.

In 2007-2008 the plan stayed on 14th rather than go East into the Central Business District. This new alignment through the CBD is much better for transit users and visibility that transit is an option.

My question was why rush to get to 14th Street? Why not go further North on 9th/10th before heading West? It’s likely too late for a change since they plan to submit to East-West Gateway, our MPO, late next month. Still, I took a look at alternatives to Delmar to reach 14th from 9th/10th.

With MLK & Cole ruled out that leaves only one other option: Cass Ave. I’ve written before about 9th & 10th through the Columbus Square neighborhood being excessively wide one-way streets — from when they served as long on/off streets for I-70. Since the bridge construction changed traffic patterns, 9th/10th are way too wide and little used. Running the rail lines on 9th/10th through the center of this neighborhood would help connect it to downtown, partially making up for the convention center (1977) and dome (1993) closing access via 6th/7th/8th.

I think more north city residents would be served by extending the line on 9th/19th to Cass. It could continue on Cass to Jefferson or use 13th or 14th to connect to North Florissant ,Connecting the development node at Cass & Tucker to downtown and to NGA West is important.

In the interest of full disclosure, by the end of this year my husband and I will very likely be new residents of the Columbus Square neighborhood, moving from our loft in Downtown West to a smaller place.More on that later. Still, I’ve been photographing & writing about the area for years.

It’s probably too late to consider 9th.10th to Cass, but I had to share it.

Readers Split On Northside Light Rail Alignment

In the recent non-scientiifc Sunday Poll readers were split on the twi competing alignments that’ll be recommended to East Wes. Planning approved a decade ago was to use 14th, North Florissant, and Natural Bridge. Since then a big chunk of the St. Louis Place neighborhood was razed for the new West headquarters of the National Geospatial Agency (NGA West), now under construction. So an alternative is to use Cars & Jefferson avenues to serve NGA West’s workforce.

Here are the results:

Q: Which of the two alternatives for the Northside light rail alignment do you prefer:

• Unsure/no answer 9 [36%]
• Florissant Ave 9 [36%]
• Cass Ave 7 [28%]

The results are lower than typical weeks, and some selected Unsure/no answer because they oppose investing in additional rail transit — even though taxpayers approved taxes to build additional rail to serve North & South St. Louis.

Advantages of Florissant Ave alignment:

• Serves 3 neighborhoods: Carr Square, St. Louis Place, & Old North St. Louis
• Taking transit to/from Crown Candy would be easier than now
• No 90-degree turns to slow down speeds

Advantages of Cars Ave alignment

• Serves 2 neighborhoods: Carr Square & St. Louis Place
• Serves more of Jeff Vanderlou neighborhood than Florissant Ave alignment
• Serves NGA West
• Could spur development of long-vacant Pruitt-Igoe site

It’s tough picking a favorite.  Would more NGA workers use transit if it stopped right out front? Would think significantly reduce auto traffic to/from NGA?

On Monday I’ll propose an alternative to the Case Ave alignment.

Sunday Poll: Which Northside Light Rail Alternative Alignment Is Your Favorite?

Today’sSunday Poll is a little different than most, instead of agreeing or disagreeing with a statement you’ll be asked your favorite of two alternative routes for the Northside alignment of  proposed new light rail line.

Below is the email I received last week: about the Northside-Southside light rail project:

After a year and a half of data analysis, study and public feedback from over 60 presentations, meetings and open houses, the Northside-Southside Study team is releasing our recommended first phase project alignment for the City of St. Louis. We knew the best route for Northside-Southside should align with community investment strategies, serve area neighborhoods and residents, and provide pedestrian access to the National Geospatial-Intelligence Agency (NGA) West campus.

Thus, the study team is recommending to the Board of East-West Gateway Council of Governments, our metropolitan planning organization, a $667 million street-running light rail investment that would run from Chippewa Boulevard in the South through downtown to Grand Boulevard in the North via one of the two North St. Louis alignment options. See map below.

• The first phase would:Serve approximately47,000 people;
• Carry an estimated 9,200 transit riders per day(4,200 of which are transit-dependent riders);
• Access 65,000 jobs within a half-mile of the route; and
• Spur possibly millions of dollars in economic development throughout our neighborhoods.

The North St. Louis Alignment
From public feedback gathered during the study, we knew any Northside-Southside route should align with community investment strategies and serve area neighborhoods and residents. Additionally on the Northside, the route should provide pedestrian access to the NGA West campus.

Both the Florissant Avenue and the newly proposed Cass Avenue routes align with community investment strategies, including the Choice Neighborhoods Initiative. These options also serve the pedestrian entrances to the new NGA West campus, Carr Square and Old North neighborhoods. Although both options fulfill project needs and provide access to jobs, redevelopment and neighborhoods, the final north St. Louis route will be chosen during the next project phase, following additional technical work and community input. The map below shows the two Northside alignment options.

East-West Gateway Council of Governments Board to Receive Final Project Recommendation Later This Summer
The study team will submit its final project recommendation to the East-West Gateway Board at its August 29th board meeting. The next step is to secure funding for an environmental study and project development, expected to take place during the environmental review process. At this time, a preferred alignment through North St. Louis will be chosen.

Overall, we have seen and heard great community support for this project. We know it will transform the City of St. Louis and St. Louis’ regional public transit system.

So the study team is recommending two a;ltermatoves North of downtown. Lots of pros & cons to each. The number of stations is the same for each. Either way Carr Square and what’s left of St. Louis Place neighborhood are served by either. So think about it and vote in the poll below.

This poll will close at 8pm tonight..

Wednesday I’ll share the results, what I see as the pros & cons of each, and if I’ve made up my mind — my preferred alternative.
