BRB - Brienz-Rothorn-Bahn is a touristic short cog wheel narrow gauge railroad, which takes rich tourists from the Zentralbahn
(formerly SBB-Brünigbahn) railroad,
from the village of Brienz up to nice scenes of the peak of Rothorn. Their historic locomotive type was the H 2/3, which they had 3
examples of, built in 1891-92 and with a maximum speed of 8,5 km/h. When they became finally unreliable in the 1970s, the BRB
ordered diesel engines (3 pieces, Hm 2/2 from 1975-87, 13,5 tons, 5,25m - 14 km/h). It soon became clear that the tourists
preferred the old style but unreliable steam engines. As a conclusion, the company finally gave in and ordered in 1992-96 three
brand new steam engines (H 2/3 15,7 tons, 6,5m, 12 km/h), though oil fueled and perfectly modern. Steam engines make absolutely
no real sense on mountain routes, but as long as the tourists are OK to pay a higher price for a steam ride, the Swiss are
prepared to provide that !
The BRB line is just 7,6 km long but yet it takes an hour for a train to climb it up. The maximum gradient is 25% or 250 promilles
and the train climbs 1678 metres higher up than where it started at Brienz. The top speed of even the new locomotives is 9 km/h.

The H 2/3 no. 7 is one of a two engine series of 1933-36: one of the "real" steam engines of this tourist attraction railroad.
It is heated with coal, weighs 20 tons, is only 6,40 m long and has maximum speed of a modest 9 km/h.
