IF YOU ARE PART OF THE CMRS AND YOU ARE INTERESTED IN THESE ITEMS PLEASE LET ME KNOW. The MTH 80-60025 HO Scale NYC Empire State Express Passenger Car Set/Box is a ready-to-go pre-built model train passenger car set in 1:87 scale. Made from plastic and diecast materials, this analog-controlled passenger car is designed for use on a two-rail system. The diaphragm on the observation car is a little loose, but it should be an easy fix. The cars that have lights have capacitors and the capacitors work very well. Please look at the photos and videos for further detail. See photos for further inspection.
