ST's plans are to start bidding now for the next fleet expansion (115 by 2021):



As for changing the design, I think it could very well happen for the ST2 extensions to Lynnwood and Bellevue. Since these extensions (the latter being a new line entirely) also include the construction of new maintenance facilities, and they will require some higher capacity trains (especially for Lynnwood, as bus truncation happens there). Getting rid of the cab cars in between the trainsets (since they no longer run 1-car trains) would be the most ideal way to increase capacity.

Thank you very much for your insights Sounder Bruce and 00Zy99. So in effect ST may become the first transit agency in the US to have a fleet compromised of articulates light rail train sets. That's pretty cool!

They already do. All Link rolling stock is articulated.

http://media.komonews.com/images/091116_derail_3.jpg

You can see how the first part of the unit has derailed, while the middle and rear parts remain on the track.

This shot shows the articulation well, too. There is one window in the central module, and the articulation points are visible on either side as vertical black bands.

Sorry I meant to imply that they would be the first to have more than two car articulation. Four or six or even eight car articulation like an actual metro trainset.

At last, Seattle loves its light rail

Seattle was the most recalcitrant city in America about rail transit — even after we built some of it in 2009. But that has suddenly ended, with the opening of connections to Capitol Hill and the University of Washington[...]



With new stations, light rail ridership soars in Seattle

The number of light rail passengers has increased dramatically since March, when trains started serving the region's densely populated Capitol Hill neighborhood and the University of Washington[...]

Sound Transit keeping close eye on crowded light-rail trains

After six years of running trains too empty, Sound Transit is suddenly wrestling with a quite different dilemma — light rail is becoming crowded enough that passengers are clamoring for more railcars[...]

I'd genuinely love to know what Seattleites consider a full train. Is it full like an Expo-line train going into Vancouver downtown during the rush... or is it full as in not everyone gets a seat? Or is it full as in you can't put a bike on during the rush? Or something else?

I find that people put up with less "fullness" when a city has only 1 train line.

I imagine it will get better when they can run more trains through the downtown tunnel.

As a comment, I took a ride on the train a while ago and I found that the signage wasn't clear ( at Int'l District Station ). It wasn't immediately clear that I was standing at a bus stop or a train stop. I am sure that will also get a LOT better when they take the buses out of the tunnel.

Either way, congratulations to Seattle ( for embracing transit ). Hopefully this will mean more lines will be fast-tracked.

For comparison, the "Canada Line" from Vancouver – YVR/Richmond runs 40m trains ( 130' ) with ( I believe ) a similar width to Link LRT.

The Canada Line currently has in excess of 122,000 riders ( 2014 ) along 19km ( 12 mi ) of track. It runs trains every 3.5 minutes ( peak ).

During peak times, is Link running all double-car 190' ( 58m ) trains? It seems that should be enough capacity if they're running the trains often enough. 190' ( 58m ) trains are almost 50% longer than Canada line, which carries twice the ridership ( albeit with shorter headways ).

Is Sound Transit going to up frequency first, or run longer trains? Me, personally, I'd up frequency ( if possible ) before increasing train length.

Frequency is maxed out already because of the at-grade segment in the Rainier Valley (where traffic signal timing is a factor), buses in the downtown tunnel (where signal blocking is in effect), and a shortage in the number of tunnel vents. Longer trains would be the best way to relieve capacity, though 4-car trains won't be needed during regular service until the Northgate extension opens in 2021. 2-car (190-foot) trains are running at all times, including off-peak, and during peak they are getting crowded; 3-car (285-foot) trains are being introduced to expand capacity.

Fullness here means no seats and no room to stand comfortably (with a few inches of space between you and the next guy). We're fairly used to crowded buses at peak, so the standard is quite low.

Signage is a huge issue because of all the agencies involved. International District-Chinatown-King Street is a complex area for newcomers and would take a lot of work to make easily navigable (without also creating visual pollution). The train and buses share the same platform anyway, and the light rail symbol should make it clear...so I don't get why you're confused. There's overhead signs with "Link light rail" and "Tunnel Buses" together pointing to the same platform, with directions.

I believe that the term you are looking for is "longitudanal seating", where the seats are with their backs to the side walls, as compared to "transverse seating" where the seats face towards the front or the rear.

Community Transit announces colors for its two Swift bus rapid transit lines: http://www.communitytransit.org/newsrelease/1663

The existing line (opened in 2009) will be the Blue Line, while the new line (to open in 2019) will be the Green Line.

Those frequencies aren't very high. They could easily double frequency even with at at-grade sections.
