With three stations fully under construction and several bridge projects on going... I can't see this being viewed as slow.

I am actually really impressed by the speed with which the MBTA is building the new stations and with how they will most likely increase service on the line once they open. However, the other part of the idea would include new cars, etc.So am I. It's great to know that they've already got three stations under construction. But with additional station and continuing to use the same standard push-pull commuter trains they're using now, run times will be higher and average speeds will be slower due to the Fairmount Line having closer-spaced stations. Running self-propelled M.U. trains, which accelerate faster than standard push-pull trains, might make for faster running times and average speeds. I'd like to see the MBTA go in with GO Transit, who is purchasing Sumitomo DMUs for service on its forthcoming service between Toronto's Union Station and Pearson Airport.

The new loco order has the escalator clause for another 20 units if they like how the first order is performing specifically because it'll allow them to expedite dumping the GP40's and their largely incompatible systems and standardize on just the 1988-93 era FP40's and new MSI46's that have a lot more parts-and-service overlap than the Geeps. I think it would be a bad idea to go DMU unless it was widespread on an "Indigo Division" where Needham, Fairmount, Stoughton, Riverside/Framingham, Peabody/Danvers, Reading, Anderson RTC, Waltham/128 all got high frequency short-turn shuttles. 1 line is just not nearly enough scale, and the T would be better off electrifying the branch, pooling its maint resources with Amtrak at a larger shared facility, and getting the better emissions and start/stop performance using their existing coaches. It would be halfway or better as good on the Fairmount as pure DMU's and would also net them a windfall of diesels freed up from loco-hungry Providence Line duty to beef everything else up. Plus they can pool that loco order with RIDOT when they initiate South County CR (and probably subcontract the T on 100% subsidy to operate it for them). That is probably what Davey was referring to with his preference about locomotive makes: if you're going to introduce a new make, electric push-pull is way way way better utilization, maintenance-friendliness, and overall bang-for-buck than a situation-limited DMU configuration.
no actual FRA compliant DMUs being manufactured now. U.S. Railcar is looking into reviving the Colorado railcar DMU,
but hasn't succeeded yet. And, the CRC DMU had some issues when it was actually tested in service. We'll see if U.S.
Railcar does any better.

Heck, that's better for any route. When the T needs to buy new Red Line cars, perhaps they should one large fleet to replace the four that are currently in service, even if it means early retirement for the 01800s. If you have a large-scale commuter rail system, it's never good to have equipment that has to be confined to just one line. That's why the T hasn't ordered electric locos or EMUs for the Providence Line. But I think if they ordered DMUs for Fairmount as well as Needham, Riverside/Framingham, Peabody/Danvers (base service on four lines), it would be worth doing. I still think that with the new stations, you're going to have an operation on the Fairmount Line better suited for multiple-unit trains because stations will be set closer together than they are now and MUs accelerate faster.

I could see it as a good way to get around SW Corridor capacity issues, but it does skip Back Bay.Not soon. There's still a decent amount of congestion mitigation to achieve in Boston: 3-track Readville-Canton Jct; 4-track Forest Hills-Readville; fix the single-track Franklin split; second Ruggles platform; high platforms at Hyde Park, Readville, Canton (and all points south). If they do that and thru trains aren't co-mingling on the same tracks with any branchlines between FH and Canton Jct there's a lot more throughput to be had for Amtrak and the Providence Line.

There are some stops on the Needham line that are so close you can see one from another (e.g. West Roxbury and Highland). That seems to work okay with the current push/pull operation. I would like to see DMU service on the lines that pass through more crowded areas (Needham being a great example of this), but more so that we could get higher frequency by using shorter train sets. Operationally, push/pull seems fine.
