Built in 1869 by Alexander Chaplin & Co. of Glasgow, this locomotive was used for railway construction. It has a vertical boiler and no driver’s cab. When used on the steep grades around Aarhus, it lacked tractive power and even needed horses for assistance. It was withdrawn as early as 1884.

Denmark’s largest express passenger locomotive. In 1937, DSB purchased 11 secondhand Swedish State Railways Class F1200 locomotives built by NOHAB (1914–1916) and used them after modifications such as converting the left-hand cab to right-hand. As locomotives were still in short supply, 25 new Class E engines were built by Frichs between 1942 and 1950. Those built in 1950 were the last new steam locomotives constructed in Denmark.

Built by Borsig (Germany) in 1898, this tank locomotive hauled passenger trains on the Zealand Coast Line (Copenhagen–Klampenborg–Helsingør), which opened in 1897. As a tank engine it did not need to be turned at terminal stations, which made it convenient in service. After the arrival of the Class S in 1927–28, it was reassigned to local lines and remained in use until 1958.

The Class P (I) was built in 1882–1883, with 12 locomotives produced by Esslingen and Hohenzollern (Germany). Many local lines were laid with very light rail (17.5 kg) for cost reasons; the Class P (I) was designed to suit such lines. No. 125 was built by Hohenzollern in 1882, transferred to a private railway in 1906, and withdrawn in 1948.

Steam Locomotive Class P (I) No. 125 — Specifications

SSBN (Stubbekøbing–Nykøbing–Nysted Banen) was a private railway that existed from 1910 to 1966, linking Stubbekøbing on Falster via Nykøbing to Nysted on Lolland. Nos. 1–5 were identical and built by Maffei (Germany) in 1910. After the line closed in 1966 the locomotives were transferred to other private lines; this unit was sold to the museum in 1997, and in 2018 it was handed over to the heritage railway MBJ (Maribo–Bandholm Jernbane), where it is now operationally preserved.

A human-powered “rail bicycle.” The museum preserves three types; this one uses the most primitive rod-driven mechanism to rotate the wheels. Behind it is coach BJ No. 665, built in 1868 by the Midland Waggon Company of Birmingham, UK, and withdrawn in 1931.

A double-deck coach built in 1900 by Vulcan in Maribo, Denmark. With no heating equipment, it was used exclusively on summer suburban services. Initially the lower deck was 2nd class and the upper deck 3rd class, but it proved unpopular due to cramped space; all cars were rebuilt as 3rd class and withdrawn in 1931.

The main exhibits are inside the roundhouse. Because the tracks fan out, the spacing between adjacent roads is narrow at the front and wide at the back, which limits framing flexibility for photography. Lighting also tends to come from one side, making exposure of black locomotives tricky.
