Scratchy: only if it was painted in Jaguars colors and had flames on the side
Pensy had asked about equipment - and it depends. Amtrak would use something different than a commuter road, which would use something quite
different than a “new starts” diesel LRT on a disused branch or street trackage. For Amtrak specifically, I’d like to see something that can couple with, MU with, and operate as a booster to a conventional train. That means AAR Type H couplers, and it may mean diesel-electric or battery-electric operation. (I don’t know if there’s ever been a diesel-mechanical locomotive designed to work with diesel-electrics.) This vehicle would probably have to be a single-level with traps, though I suppose Amtrak could order both single and bilevel versions.
I’ll reiterate my “doodlebug” suggestion of a 1500-2000 hp powered baggage car, capable of towing 3 coaches at track speed. I don’t see Amtrak starting new service with anything less than two coaches and a baggage car, so this ought to be enough.
