The Railway Museum (Dutch: Het Spoorwegmuseum) in Utrecht is the Dutch National Railway Museum.
It was established in 1927 and since 1954 has been housed in the former Maliebaan station. The museum currently owns a large and varied collection of rolling stock.

Small Diesel-Hydraulic shunter NS 103 preserved at the Het Spoorwegmuseum / Railway Museum in Utecht Maliebaan former Station. July 15th, 2022.

After a few proto-shunting vehicles, the Materieel en Wertkplaatsen of NS, led by Ir P. Labrijn, designed a very useful "locomotor", which can be used for shunting with freight wagons in a simple manner. The locomotive has a petrol engine from the Heinrich Kämper Motorenfabrik AG, Berlin - Marienfelde (D) that drives two axles via a mechanical clutch with friction plates and chains.
It is no longer necessary to order an expensive steam locomotive or keep it under steam, because the locomotive is relatively cheap to purchase and can be started and deployed at any time.
The operation was extremely simple, the locomotive could after a short training be operated by a foreman-shunter instead of an expensive, full-fledged engineer with his apprentice engineer (stoker).
After the war, most locomotives were withdrawn from service. That happened with the 103 in 1947 or '48, after which it was sold to the NV Staalwerken 'De Maas' in Maastricht.
In the 1970s, the faulty locomotive was donated to the SGB, who did not overhaul it due to other priorities, but did fix it up. On that occasion, the 103 was given the name 'Beer'.
Later again, the 103 was handed over to the Railway Museum. At the Revisiebedrijf in Tilburg, the petrol engine was replaced by a DAF diesel engine and the mechanical drive by a hydraulic one. Externally, the locomotive was returned to its original state, with the name 'Beer' removed again.
From 1989, the 103 was used as a pulling or pushing force for tours with two tram carriages of the Wiener Lokalbahn through the then renovated museum by the Railway Museum.
In 1996 the diesel engine was worn out, so the locomotive was taken out of service.
