The trains still layover there, they just cut revenue service and demolished the station, last service there was in 1994. The wye for turning the train is there as well. But the Quincy and West Quincy stations were both stops, they didn't skip Quincy, IL when West Quincy, MO was the terminus. So it wasn't a relocation, they just cut back service. I'm not sure what the passenger numbers to West Quincy looked like but I imagine it was pretty tiny. West Quincy is a town of like 500 or 600 and there aren't really any bigger towns very close by.
