Those auto racks are owned by TTX, although they bear name of other roads. TTX leases them out. I have never understood why they have other road names on them if they are owned by ttx. Here is a Santa Fe auto rack that belongs to ttx, hence the ttx logo on the frame and ttgx reporting number.
thanks for the info, that answers one question I've always had. But what about the fallen flags, I see conrail, southern pacific and other racks all the time, with no reporting numbers on the racks themselves just the ttx number. I've only seen road specific reporting numbers on NS, some CP and some CN racks.
Thanks norfolksouthern37, something to watch for next time a train goes by. The conrail racks I was referring to look similar to the one pictured below. Does the same apply to these, reporting mark on the end?
