The LTM Series 21-35 consisted of 15 standard gauge steam locomotives, built between 1922 and 1925. They where built by Hanomag, and used by the Limburgsche Tramweg-Maatschappij on varius tram routes in Limburg (NL). One of these engines was preserved, and can still be seen in operation at the Hoorn-Medemblik heritage railway.
The MOC is built in 1:45 scale, and can be motorised with an 9v, PF, or PU train motor. There is no room for a battery box in the loco, but there is space to route the cable out trough the back of the cab to connect to an external battery box in a wagon.
