The Härtsfeldbahn is a metre gauge railway in southern Germany, from Aalen via Neresheim and Dischingen to Dillingen in Bavaria. The railway was opened for commercial traffic in 1901 and extended to Dillingen in 1906. All train traffic was suspended in 1972. In 1985 the association Härtsfeld-Museumsbahn e.V. was founded and in 1986 a Härtsfeldbahn museum was opened at the station house of Neresheim. In 2001 museum trains started again rolling on the Neresheim to Sägmühle part of the line.

This diesel locomotive "Jumbo" has a varied history. It was built by the company Jung in Jungenthal in 1954. It was intended to be sold to Brazil and therefore it spent weeks on the Härtsfeldbahn for trial runs in the spring of 1954. But it never ended up in Brazil. Instead it was sold to the Finnish company Lohjan kalkki in Virkkala together with another similar machine. Jumbo worked in Virkkala in southern Finland until 1972 until it and its sister machine both were sold to Switzerland. 1972-74 it was modernised and rebilt to metre gauge and it ended up at the rail company LSE, Luzern-Stans-Engelbergbahn, where it took care of the cargo traffic of the LSE line. But year by year there was less and less cargo traffic and then finally in 2005 Jumbo was sold to Härtsfeldbahn.

Museum traffic on the Härtsfeldbahn is quite often performed using this old motorwagon T33. T33 was originally delivered to Kleinbahn Bremen–Tarmstedt in 1934 but it has been later thoroughly rebuilt.

Härtsfeldbahn has at least three of these unmotorised wagons intended for use with a diesel motorwagon such as the T33 shown above. At least two of them have been taken over from the island railway of Langeoog, North Friesian islands.

The museum trains are often also being pulled by a steam locomotive and then for example this old coach comes to use. This HMB5 coach was built by the Waggonfabrik Herbrand, Köln, 1909, for the Süddeutsche Eisenbahn-Gesellschaft.
