    I-90 Interchange Improvement Project & West Station | Allston

    Because South Station has direct road and transit connections to just about everywhere, including BU and Harvard and including all of the rest of the urban universities not named BU and Harvard. It's the densest connecting node in the whole city with the superset of demand, and that's why the...

    Looks like it's supposed to be an access road to the layover yard below, given that there appears to be pavement on the ground level continuing from the same trajectory after the deck ends. Though I have no idea how it descends below-deck because there's nothing but station tracks underneath...

    Harvard seems to think that the functions of what they build there will have a built-in audience for a one-seat instead of two-seat to the LMA. And that's a reasonable assumption if what they build there indeed does (biotech?), because it's not that long a route and should have decent schedule...

    I wouldn't read too much into that rumor. The CSX employee on RR.net has already walked back the additional rumor that CSX was going to be installing an engine turntable at recently-cleared Barbers Yard in Worcester, so either the sources aren't too reliable or CSX is still brainstorming a...

    It's not "many" private shuttles. It's 3 routes: Harvard campus shuttle, for Harvard I.D. holders LMA campus shuttle, for Longwood Collective I.D. holders Kendall+Lechmere shuttle, for MIT I.D. holders and a so-far unspecified (Charles River TMA???) Kendall biz collective That's it. The...

    The 66 was discussed at length over the last decade, and the T concluded that it would be much much too disruptive to divert a Key Route the degree to which it would have to divert to loop at West. The BNRD only reaffirmed that decision. There will never be a 66 stopping there. It's simply...

    Wait a minute...I wasn't even paying attention to the new renders of the upper level. Somehow those wasteful busways increased in capacity from 6 to 10 simultaneous bus berths in the latest redesign. Before: After: Again....the only buses that are actually going to use that piggish waste of...

    New Red and Orange Line Cars

    NETransit updated to show 2 more Orange acceptances (up to 130 active cars) and 2 more Red acceptances (up to 26 active cars). That's probably the reason why there are at long last 4 active Red sets, as they can now run 4 with a loss of any 2 cars down for warranty mods. 10 Red cars...

    There's not really going to be any inbound/outbound schedule dependencies on an express track that short. Minimum thru-Worcester headways are going to be :30 bi-directional, meaning there will only be an expressing train passing one direction or another every 15 minutes. Amtrak's tippy-top...

    Here's a much saner render: No layover. Build Readville Yard 1 as permanent instead of temporary, and you net more layover spots than the crippled plan here. 1 center express track. No crossing conflicts between locals and expresses. Side platform for mainline inbound, island platform for...

    The only CSX Framingham yard with slack space is the south yard, CP Yard. That's only used these days by a lone transloading customer and for temporary empties storage; about 90% of it is unused. Unfortunately that yard is only accessible by a reverse move that crosses Route 135 at-grade...

    Here...here's where you zero-out the Beacon Park layover. The T has already contacted CSX for permission to construct a temporary 5-track layover yard on a weed-choked derelict portion of CSX Readville Yard 1 along the NEC that's currently unused by CSX, done while they disrupt the current...

    Wait...so we've gone from this: 2 express tracks 3 station tracks 4 layover tracks (8 berths) ...to this: 2 express tracks 4 station tracks (!) 2 layover tracks (4 berths) What in the everloving @#$% is going on here??? Halved the layover capacity yet again, yet bloviating without end...

    Hot...garbage. It assumes an agonizingly slow multi-decade full rollout of clock-facing Regional Rail (2045?!?), which is mostly just an ops change not an equipment change, so the midday storage figures are wildly overinflated. And it excludes the expansion of Readville Yard for the Southside...

    Green Line Reconfiguration

    Marginal was re-laid in its entirety when the Pike came through in 1964-65 and required widening of the rail ROW. Prior to that the South End street grid abutting the rail canyon was very different, owing to just how many blocks were nuked in the name of urban renewal. There was a street there...

    Green Line Reconfiguration

    There's no room for a pocket turnback track. The current pocket w/inspection pit is only 1 car (and will probably go away at some point because it can't fit a Type 10), and the area is riddled with support poles. Don't forget, Park used to have 2 loops...the current inner-to-inner track one...

    Green Line Reconfiguration

    That's probably not going to be possible. The '05 EIS frustratingly doesn't include a total width measurement for stacked Chinatown, but it does offer one for almost identically stacked Boylston: 45'4" from outermost concrete wall pour to outermost concrete wall pour (meaning, subtract at least...

    Green Line Reconfiguration

    In 2003 a combo station at the mid-block was explicitly considered, as were Alts. with the combo stop and no short-turn loop. All were rejected due to incompatible grades, excessive dwell times, and the fact that it provided zero cost savings over doing 2 stations because of the complexity of...

    The police will refuse to do it, and become confrontational with the Mayor. That's pretty much how it went in NYC and several other large cities whose departments have given up the ghost on basic traffic enforcement. The larger the department, the more unaccountable they become to willful...

    Green Line Reconfiguration

    Green Line has the same general max allowable grade as Silver Line: 6.0% for up to 2500 ft. length. Recommended max grade is 4.0% for unlimited length, which is actually 1% less than it is for Silver. While LRV's have much more tractive effort than an electric bus, steel wheel slip becomes an...
