Working on a MOC to upgrade my Railway Express that I got back in 2000 to run off of the new Power Functions Hub and Motor. Really happy with how it has turned out. The drive motor is in the rear and the lights snake through the fuel tank and forward bogie to the headlights. Even made a little engine to sit in the back that can be accessed by opening the rear doors. submitted by /u/Wolfspane [link] [comments]
