The MaK GDT is a large-volume diesel railbus (German: Großraum-Dieseltriebwagen or GDT) that was first built in 1953 for private railways in Germany.
The GDT was developed in the early 1950s by Maschinenbau Kiel for light and private railways. Eleven units were built as driving cars (Triebwagen or VT) for north German private lines.
The Danish railway company Odsherreds Jernbane was supplied by MaK with two similar vehicles in 1961. These were designated as Mo 25 and Mo 26; they had 66 seats, were fitted with gangway connections and had a top speed of 120 km/h (75 mph).
The firm based the coach bodies on the design of the centre-door coaches of the Deutsche Bundesbahn. The engines each drove an inside axle on the bogie; only on the VT 81 delivered to the Kiel–Segeberg Light Railway (Kleinbahn Kiel–Segeberg) did the engines drive both bogie axles.
