Homemade train / rail cart riding on abandoned railway tracks

Last summer, I build this wooden rail kart from scratch. Its powered by a 8HP briggs and stratton engine. The power is transmitted to the wheels by a selfmade transmission with parts from a lawn tror. It can go up to 50km/h (31mph), the speed is not limited by the engines power but by the weakness of the wooden base. (it starts to vibrate quite alot around 50 km/h).\r
The 20km long railway has been abandoned for more than 10 years and is quite steep for a railroad. The maximum steepness is 20mm/m (2%) but it is often close to 10mm/m (1.5%) \r
Fun f:\r
The last train that drove on this railroad never got to the train station, as the modern passenger train got stuck on the 20mm/m part of the tracks because of the wheels losing grip!\r

Unfortunately, some people destroyed it and stole the valuable parts, there is not much left of it, only the wooden base and the seats. \r
