What year were metroliners removed from service on NEC? And also, I used to see Detroit trains with metro-cabs through the 90's. Now Detroit trains have two units, one on each end. Why use two units when the system is running low on money when one unit worked ten years ago (one with less power on similar size trains). It seems Amtrak has moved away from cab cars, even though others still use them.
I've been perplexed myself by Amtrak's waste of locomotives. They claim that they can't afford to run two P42s on the Texas Eagle, and yet numerous short haul trains can run with a P42 on each end? Why not make use of all those ex-Metroliner cab cars that are sitting in storage?
The Kentucky Cardinal, when it was still running, was the most ridiculous example. Two P42s for a single Horizon car? If they couldn't wye the train, then that would have been the obvious place for a Metroliner cab car in place of the Horizon.
