10-12 months??? That's an insanely long disruption for a bridge as small and cookie-cutter as that. I get that the only freight route to Maine doesn't allow for a weekend-shutdown rapid replacement, but it shouldn't take so freaking long to replace it one track at a time. That's also the...

1) Trains still need to park overnight. More trains than today if there's going to be :30 Regional Rail and :15 Urban Rail service right from 5:00am and in the reverse peak direction. So that means there has to be some sort of substantial central layover somewhere. The Layover Analysis report...

This is what the South Station Expansion DEIR says about mitigations to the Tower 1 chokepoint. Basically, it's the very slow speeds that lead to a lot of crossing conflicts. If the trains cleared the switches at 25-30 MPH instead of 5-10 MPH, there'd be a lot more flexibility as the switches...

They already did a Layover Analysis 11 years ago attached to the South Station Expansion scoping study that detailed exactly what future layover needs were going to be. Widett Circle was evaluated for that at the time but eliminated from consideration due to the (then) land acquisition politics...

Quincy's cost is scandalous. Quite literally a scandal, as the whole process was re-bid when the initial bids came out insanely high in a way that the bidders could not fully explain. While the costs for these types of projects have unfortunately increased lots, there is no way in hell Quincy...

Not really. The express tracks were going to split to the south side of the ROW, the layover was going to be in the middle, and the local tracks were going to split off to the north. It would've precluded putting another mode in the middle at all the way the revenue tracks were...

It was originally designed to ease the southside space crunch pre- Widett purchase, when they were scraping for any nooks-and-crannies they could get. Now that they have Widett Circle in-tow, that's going to be the much bigger and more centrally-located layover. And the Secretary alluded to as...

https://commonwealthbeacon.org/transportation/transportation-secretary-gives-unfiltered-take-on-challenges/ Looks like at least some major elements of West Station are going to have to go into redesign. Transpo Sec. Tibbits-Nutt formally came out against the T layover yard that was inverting...

L.A. Metro in January passed on all its options for their CRRC HR4000 HRT cars instead, opting instead to accept a brand-new HR5000 bid from Hyundai-Rotem. The L.A. pilot units were assembled in Springfield as well, though they were supposed to shift to CRRC's Chicago factory midway through the...

Only a crewmember can exert direct control over which doors are bypassed in a normal opening sequence. It can't be an auto-sensor thing.

Yeah...what is the 64's actual routing in this universe? Central Sq <==> Cambridge St. <==> Cambridge St. South <==> Malvern Connector <==> Malvern (or Alford St. ==> Babcock ==> Comm Ave. in one direction) <==> Brighton Ave. <==> N. Beacon??? That opens up a half-mile transit gap on Cambridge...

They aren't considering the 66 as of the most recent presentation, and now would be the time to propose if it were feasible that given the BNRD's advancement. So that is a big red flag that the 64's detour is still projected to be a schedule-killer. As I said previously, the 64 already being...

You could dig under one track at a time and "lane-shift" around the temporarily single-tracked railroad. Stabilize the soil around the remaining one track while pouring a complete half of a tunnel, then shift the track onto the completed tunnel roof (properly stabilized) while doing the other...

https://www.inquirer.com/transportation/septa-train-car-contract-canceled-20240412.html SEPTA pulls the nuclear option on CRRC, outright cancels its order for 45 bi-level commuter rail coaches after the pilot units assembled at Springfield were plagued with so many problems that no deliveries...

The vestibule ends of the Horizon cars are more exposed to the elements than Amfleets, so there's been a longstanding problem of water collecting leading to slippery conditions. And the doors often get stuck when it's icy because of similar water seepage. Chicagoland has been complaining about...
