Zeuke FD50 streamlined 2'C, 1950's. Several interesting features- it's made largely of Bakelite, including the wheels. It was designed to operate on 3-rail track with the outside rails isolated from each other, which was used to implement reversing. To make it operational on ordinary 3-rail track I isolated one of the two outside rail pickups (after checking which one would result in forward operation). It runs fine, and with the recent removal of the last of the Lionel switches on my O gauge loop, it runs without stalling (it didn't like the gaps in the Lionel 022 switches). In the underside photo you can see the two sets of triple sliding pickup shoes (provides some track cleaning!). The three coaches that came with it are also Bakelite.
