Are PV cars ever connected to trains when they are run in the push direction? If so, where are they placed? Behind the engine? I would assume they can't be the lead car, since that would require a control stand (and have to be hooked up through the train to the engine). They also couldn't be put next in front of the engine (i.e., between the engine and the last "regular" car), since the power from the HE power plant as well as the signals from the control equipment would have to be routed through the PV car. But would it be practical (or even possible) to put a PV behind the locomotive (i.e., with the loco placed between the PV and the rest of the train)?
If PV can't be used on a pushed train, would this mean that some places, where all the trains are either pushed coming in or pushed leaving, would be inaccessible to PV equipment?
