It's still pretty much afloat, it's just that the focus right now is on the Transbay Terminal Tower because it is a great priority at the moment, especially that it will house bus operations by AC Transit, Golden Gate, Greyhound, Muni, SamTrans, and WestCAT. Just wait until the funding is complete for the Caltrain extension to happen.

Currently Caltrain is planning to upgrade their service from diesel to electric, and a big question is if they are going to match the proposed HSR line in platform heights. The reason this matters is if HSR and Caltrain will have separate or shared platforms at the Transbay Station. Shared platforms are preferable in order to operate maximum HSR and Caltrain service.

Does anyone know if there will be an underground concourse connecting the Transbay train station to the BART/Muni station on Market St?

No plans yet, and as far as I know there won't any underground connection

Can someone explain how or why they've added gauntlet double tracks? Are they to allow passing through the station a safe distance from the platform?

And freight trains!

Actually, it will be a shared portion for both SMART and freight trains, especially a good portion of the line is single tracked. Such provisions have been made to allow one train to pass through, effectively allowing two-way operations where needed. The consequence of such a concept is that when one train gets stuck on a single-track portion of the line, trains from either the northern or southern end will eventually get delayed since there will be no double track to bypass the stranded train.

And by the way, here are just a handful of pics I've taken of late... for more, just ask me for the link. The theme: a handful of New Flyer Xcelsior buses...

San Francisco Muni: operates the XDE40 variant (around 100 in service, progressively being introduced)

Aren't gaunlet track are too expensive in operation, compared to retractable steps on rolling stock?

I was explaining the reason for the GAUNTLET track, which is to allow freight trains to pass a safe distance from the platforms. The double-tracking along the lines are to allow both freight and passenger rail to pass each other. The advantage to single track is cost. Sacramento started with much of its light rail single-tracked, and has since double-tracked much of it as the mode of transit became popular. With limited funds, it becomes an issue of cost-benefit. Double-tracking a rail line nearly 40 miles long is expensive, prohibitively expensive, especially when the project already, to the taxpayer's dismay, has to be phased due to escalated costs.

Maybe so, but retractable steps are CORNY, plus they add time to stops. The emphasis of this line is passengers. Passengers first, freight second.

You want to mount retractable steps(very prone to mechanical errors) on every train door.. of every train(that's a lot)? .. in stead of just having a few switches?

Well, switches may cheaper to mount once during construction, but after that they needed to be changed periodically. I saw one analysis stating that steps are cheaper... Yeap, here it is - http://www.scribd.com/doc/176758445/...g-for-Caltrain

If they are properly synced with door operation - they don't.

We can argue about passenger and freight ops on the Sonoma and Marin rail service... but, how will SMART be able to provide efficient service if most of the track is single-tracked and you will only have gauntlet rail to rely on? I think of gauntlet rail as having a double purpose:

- To allow freight trains to wait for the SMART train to go by, especially at stations; and
- To allow two trains to run simultaneously in urban sections

Double tracking could allow even more trains to operate on the line (especially that Golden Gate owns the rail alignment). However, at what cost will it bring to us, the taxpayers, to make it happen? I would say it is definitely needed over time, but we'll see how the gauntlet system work first and work it out from there on how to improve rail service.

A study has been conducted to extend the currently under construction Central Subway to Fisherman's Wharf. This has been talked about and the North Beach community wanted a station at Washington Square. This project is still in its infancy and no funding is present. This could be a ten year project.

Proposed routes as follows.

Thank goodness this is under study. When I heard that they were digging a tunnel all the way to North Beach, and not putting a station there, I nearly lost it. What a waste that would be. Let's just hope they get some kind of political support behind this before they take the tunneling machine out of there.

I'm not sure which of these alignments makes the most sense; I'm not the biggest fan of one-directional loops, but it would be great to get all three of those stations. Thoughts?
