In Viseu de Sus (Maramures County) there is one of the few (or maybe the only) remaining mountain railways with steam traction in Europe. The service began in 1932 for logging and passenger service. Today only the tourist trains are steam powered, all others using diesel fuel.

The trip is almost 22km long and the scenery is green, undisturbed. During the return journey, the last coach partially derailed. The situation was solved without delay, with the aid of another locomotive, a hoist and a pair of wedges.
