Alstom CTDOT Single Level Passenger “Adessia” Coach Order

Indeed.

The last gen of DMU, the SPV was Amfleet compatible and a SPV would run on the tail end of of some Amfleet
trains to allow through service to New York in the early 80s.

If a DMU variant of the upcoming Alstom coaches appears, it would basically be the proposed M-7 DMU concept
finally come to life.

If these single level coaches have the same dimension as the M-7, they would be perfect a future for LIRR, able to
fit the ESA loading gauge.

R36: Yes-The Budd SPV 2000 cars were basically a powered Amfleet or Metroliner-type car...
They were built to be completely compatible with the Amfleet as most know...

There was something more to the Amtrak NEC move: The NEC train used terminated at Philadelphia
(Train #193 BOS-PHL) leaving NHV at 8:05 PM - Arriving PHL at 11:50 PM...This allowed the Budd Company
to inspect and maintain the SPV 2000 cars under their early 80s warranty period for CTDOT...

The Bombardier M7-type design DMU would be a good application for services on the LIRR such as
the Ronkonkoma-Greenport and South Fork Commuter Connection (Speonk-Montauk) replacing
the short locomotive-hauled one or two car trains now used - for CTDOT the Waterbury Branch looks
to be the best fit for any future DMU cars...

It will be interesting to see the upcoming fact sheets for the new CTDOT cars when they are available...

Unless the 3-headlight rule since 1997 (added ditchlights) provides sufficient coverage.

So the Brits, who were manic about yellow front ends for safety, have recently said that they will allow darker front ends if the correct light package is chosen. Evidently they find the correct combination of bright flashing lights more effective than yellow paint.

Kind of ironic that they had the worst light packages of any developed nation - it was headlights optional for quite some time.

They now look a lot more like Japanese EMUs than North American push pull coaches. I have no idea why they have to look so “boxy” looking, but there you have it. Additional graphics on the Alstom website indicate that this is their official single level commuter coach offering, not just a customized ConnDOT offering.


The addition of the small humps on the ends of the roof (as shown in the NGEC PDF) make them look more like the Acela coaches. Link them together and you’ve got a successor to the demotored SPV coach

I think they just look more like their EMU counterparts, at least they're *slightly* more curved than their predecessors lol. I don't think the UK Electrostar or ScotRail Hitachi EMU look would really fit the NEC.

I wonder if maintaining this form factor has to do with the ability to bury the cabs in consists, and more importantly allow them through to Grand Central if need be (where the Park Avenue tunnels require front doors).
