Fiat 126p Draisine

In many countries, including Poland, draisines are used for short distance rides on railway tracks, in order to check if they don't need repairs. Some of them are powered by hand, using two-side lever, others by electrical engines, and some are based on road vehicles, like this Fiat 126p-based draisine, which arrived for Steam Locomotives Parade in Wolsztyn (despite the name, draisines and other rail vehicles were also involved, but steam locos were the main attraction).

(note: the name SP42 on its side is just a decoration. SP42 was a modification of SM42 locomotive, adapted for use in passenger trains by adding heating systems, unaviable in normal SM42)
