Re: Driven By Customer 'Service' Parte Dos
Way more than Blandford. Every B platform can do 3-cars today (some considerably less comfortably than others), but every single one of them sandwiched between grade crossings (BU East, Harvard Ave., Chiswick, Chestnut Hill Ave.) are too short for quads and would either have to move or have the entire roadway reconfigured for fewer grade crossings.
It's a prohibitive amount of reconfiguration when per-train capacity isn't the problem...front-door-only boarding, train schedules/bunching, and messed-up stop spacing are the problem. The B is not growing on any sort of curve where the capacity needs are going to DOUBLE end-to-end on the same exact headways as 2-car trains are running today. That's ludicrous. If more capacity is needed then they should be zeroing in on 1) installing a short-turn yard between Harvard and Griggs for Comm. Ave. rebuild Phase III to flush the innermost headways @ 3-car, and 2) evaluating supplemental thru-routed trains off the C or D to flush the BC schedules fuller...and backstop those highest-ridership/highest-growth portions of the line on either side of the hill accordingly.
The grade-separated lines (D to GLX) are the ones that could/should get quads to flush the subway. The B just needs permanent triplets, and eventually the too-short C platforms (Washington Sq. because of the U-turn grade crossing and Cleveland Circle because of the Ayr Rd. crossing) should get fixed to allow triplets. E...out of luck unless the VA Hospital is willing to sell a strip of parking lot to widen out outer Heath Loop; that's the limiter for >2.
The amount of capacity increase per train that comes from +2 D cars at peak and +1 B/C is so high that tactical nuclear strikes like mowing down every single surface platform for future proofing OCD is a useless distraction. One that directly inhibits your preference for more crosswalks on Comm Ave.
The only things they need to do are churn through the ADA and fix the platforms that pinch so narrowly at the ends they're awkward as hell for 3-cars. Blandford is fine for opening all doors on a 3-car set if they put a fence between the roadway and eat the shrubbery to widen out that impossibly narrow platform closest to the portal. Finish that and streamline where streamlining's needed and the B is primed for all the capacity bump it'll need without overkill or screwing up the station spacing for some perfectionist notion of future-proofing it'll never need.
