I live a block off the rails along this line. Delivery hours could be any night time hours. earliest usually around 10:30 PM.
Before Warminster, there was one place that takes delivery, at county line road. It is a Pasta production plant, at least, it was.
I think the orignal brand sold it off, but there is still activity there, there are always 4 or 5 rail cars parked outside it.
street road was the other area in the immediate area with company(ies) that took delivery. I assume there has to be occassional deliveries further north, I have seen hopper/tank/box cars. Usual delivery size was 10 freight bearing cars.
I'm a late nighter, I'll see if I can catch a train go by. I didn't know if it was the economy or what, but it seems
the train lenghts have decreased. I'll see who's engines they are
