It's a 3% grade on the Mystic Bridge approaches, steepest on the whole Commuter Rail system. You can't have more than a 2.08% grade on the platforms (p.12) and still be in ADA compliance.

South Station was extensively renovated 1988-89. That's when the full-high platforms were installed and the current waiting area was reconstructed. So there may have been disruptions such as the waiting area being a mess or partially out-of-commission and platforms being taken out-of-service...

Consultants managing consultants managing contractors. Every individual entity had cover for not looking into such trivially important things because the chain of command was so muddled, and they all make money on change orders so YOLO. If Caltrain had stronger top-down management it could've...

Oh, they're doing that too. They're spending an absolutely bonkers $80M for one 4-car BEMU pilot set for their un-electrified San Jose-Gilroy tail. Which might cost them close to a half-billion dollars to completely battery-up. It was horribly managed. They were originally scheduled to do it...

It depends heavily on whether a D infill would require any re-spacing of signal blocks to fit in a new station block. Involve the Signal Dept. and signal mods, and the price jumps quite a bit higher.

Yes. That's exactly how Brightline does full-highs on a freight clearance route. The platform edges lack a wood bumper edge and the Siemens coaches have platform extenders. The problem is that you'd have to have an almost-universal fleet of platform-extender rolling stock to really make it...

Why would we be following the street grid for anything rail when the Eastern Route is right there? I mean...it's one thing if you want to divert off-ROW after Sweetser into Downtown Everett. Crayon away at those dreams for what they're worth. But for actually getting across the river and as...

NNEIRI specs exactly that as one of the travel options: an Inland meeting the existing Vermonter at Springfield. They envisioned the whole shebang as not the BOS-MTL direct being the be-all/end-all, but the timed transfers to the Montrealer and the expansion NHV-MTL slot contributing to net a...

More Albany lash-ups would require enough capital funding to uprate the track class to Albany from Class 3/59 MPH to Class 4/79 MPH. It's planned Worcester-Springfield and will shrink Boston-Springfield travel times from 2:28 to 2:03, but you'd need a MA funding dump to do Springfield-state...

They only stock enough replacements in the warehouse at any given time for big-deal things like a window break, not for improving general aesthetics.

The 900-series Kawasaki bi-levels are particularly prone to cloudy windows since they're now 19 years old with no rebuild date in sight. Those are mostly confined to the northside nowadays. The 700/1700-series Kawasaki rebuilds and the Rotems all have much newer windows, and the single-levels...

$55M of the $148M increase in the last CRRC contract revision from May was already a tariffs adjustment. This isn't a new thing in the slightest. To even establish bounds for a future increase, you first have to determine how many cars are paid for by January 20 at the earliest (or...

Tell that to Breda.

It likely wouldn't have been HRT Red Line to Waltham, but an extension of the Arlington Heights trolley west along the Watertown Branch, where the trolley could've handled the grade crossings and closely paralleled the (then-trolley) 71. The reason it wasn't proposed as such in the '45 plan is...

They might be going for scrap at Schnitzer Steel in Everett via CSX. 4 others in the retired 1600-series Bombardier cab cars were scrapped there earlier this year.

The window sizes would be custom for each rolling stock make, but things like the rubber sealers and general methods of window replacement are probably standardized so they have a (weak) argument for staying with what they've always done for window selection on the Type 10's. Plenty of other...

Yes. Take the innermost busway berth at the station for the extra track (reshape the other two), refashion the current CR platform into an island, diet/eliminate Old Colony Ave. coinciding with a Columbia Rotary redesign, and drop the extra track on the Old Colony Ave. side of the overpass...

A better way of doing Red X instead of deinterlining is alternating pairs. You'd have 3-minute headways on each leg of the X, but use all of Columbia Jct.'s potential so that any one north-to-south routing achieves 6-minute one-seat headways. So say a Phase I build of the X pushes a subway to...

https://sunnysideyard.nyc/ The Sunnyside Yard air rights vision in NYC offers up a useful comparison for why the BP vision is so half-cocked. Housing (and affordability of housing) -first, transportation hub and mobility second. Small, walkable blocks instead of chunky blocks and stroads...

The parts warehouse is consolidated across the rapid transit division, so there is a degree of maintenance centralization for keeping replacement parts in-stock.
