Class T0 (Locobase 9919)

Data from Christian Lindecke [] (visited 30 August 2006) See also [], last accessed 6 August 2017.

Very interesting small freight tank engine design that replaced some 0-4-0Ts on branch lines. They were near-duplicates of the ten T0 built for the Hannover by Henschel and shown in Locobase 20241. Unlike most earlier 2-2-0 arrangements, the leading truck wheels on the T0s were nearly the same size as the drivers and the two axles were placed at the ends of the frame. The lead set of wheels had diameters of 1,000 mm (39.4").

The result was a little engine that could hit up to 60 kph (37 mph) and proved itself a useful engine for light traffic into the 'teens. It resembled the motor trucks that would replace such small steam locomotives with in 20-30 years of the T0's introduction.
