The steam locomotives of the series 99.18 were to operate on the Feldabahn built in Thuringia. The locomotives were included in the numbering scheme of the Reichsbahn under the operating numbers 99 181 to 99 183.
The T-40 replicas were used on the Feldabahn together with the older T 33 machines. A total of three machines were delivered.
The wheels of the three central axles were coupled to one another via external coupling rods, the end axles ( Luttermöller type with lateral displacement) were driven via internal gears from the axles further in the middle.
The locomotives remained on the Feldabahn until 1934. After the gauge change, all three machines came to the Hildburghausen – Lindenau – Friedrichshall railway line . In 1944, 99 183 was taken to Eisfeld and used from there on the route to Schönbrunn . Later this went to the Spreewaldbahn . It was last used in 1969 on the route of the former Gera-Meuselwitz-Wuitzer railway . In the last few years the gears had been expanded to the end axles, they ran as running axles. The other two locomotives, along with the rest of the vehicles and the track material from the Heldburg narrow-gauge railway, were sent to the Soviet Union as reparations in 1946 , where their track is lost.
