I know I've said this before, but since we're talking about speeds and trip times on the Cape, I don't get the Cape Flyer not stopping in Sandwich, when there's an existing station with a mini-high platform that's a ten-minute walk on quaint streets with sidewalks past all kinds of restaurants to the Dan'l Webster Inn, the Glass Museum, some B and B's -- a perfect train destination. The station isn't a bad bike ride to at least one nearby area of beach houses and such, too. Adding what, five minutes, to the total trip time seems worth it to add a whole new group of potential passengers without needed to build anything.
CC&H used to run connecting trains to Falmouth; they'd meet their own trains and the Amtrak Cape Codder at Buzzards Bay. I don't know how many years they did that. It seems like it wouldn't cost much or disrupt the landscape around the bridge much to build a basic set of short high platforms and sidewalks for "cross-platform" transfers between trains stopped on the Hyannis and Falmouth lines. Wouldn't even have to cut down most of the existing trees or pave the whole area between the tracks: just connect the platforms to each other. Or maybe the transfers could happen in Buzzards Bay and both trains could cross the bridge one after the other on the same closing. How close can trains follow each other at slow speed? Once the Hyannis train had cleared with switch and the switch was set for Falmouth, could the Falmouth train follow immediately, without needing signals? One bridge closing, two trains, in other words.
