No. 207 is a locomotive of the NSB class 21, a light passenger/mixed traffic type, built from 1909-1919. 42 type 21 were built in all, by Hamar, Thune and NOHAB, Sweden.
No. 207 is probably, at least originally, of type 21a, as were nos. 205-206, both working at Vossebanen (from Bergen)from 1938. These, too, were built in 1909, but by Thune.
I.J/ Gubberud (Vossebanen), Norsk Jernbaneklubb 1983, gives the following data for class 21a:
Total (loaded) weight: 58,9 tons
Coal capacity 3 tons
Max. speed: 60 km/h.
Niels Jensen, Damplokomotiver, Fr. Clausens forlag,Copenhagen 1971, (this time for the 21b) gives the same speed,driver diameter and coal capacity, but states the empty weight as 45,4 tons. As he gives the loaded weight at 56,1 tons (of the two informations on loaded weight, one is probably incorrect, as the b was more probably heavier, rather than lighetr, than the a), the difference in empty weight between the two subtypes is not likely to be very substantial.
