Very nice modeling, Chris. And I tip my hat to you for thinking to model such a train.
Since I live out on the prairie, I'm not even slightly familiar with the trash pickup operation in the New York subways. Does this train get pulled by a dinky diesel locomotive? Or is it a little electric locomotive? Is this strictly a nighttime operation? Do workers, by schedule, collect garbage at a certain hour for that station, and stage it at the edge of the platform for collection by this train soon thereafter? Does the train have a regular schedule of its own, so that it fits between regular subway trains without delaying them?
Please pardon my ignorance. This is very interesting to me.
And -- saving the big question for last -- does our own Ben (blueline4) ever run this train? Maybe he'll tell us.
