Bachman HO NS Norfolk Southern F7A Diesel Locomotive A/B #4271. This is a nice used set, these are very clean and almost like new, not sure if they were used or just on display, they were in a display case, no box included. These were tested and work great and headlight works fine as well. There is a one small missing paint in the white nose next to the headlight, one coupler has a loose spring also. I’m not a train guy so not sure what else to look for so if you have any question please ask?
