Modernized Steam Locomotive “Heidi” on the world-famous Albula line of the Raetian Railway


Concluding the tune-up period of commissioning the modernized light-oil fired steam locomotive type G 3/4 Nr. 11 worked several test trains on the famous Albula line, one of the few railway lines declared a world heritage by the UNESCO. The attractive metre gauge line constantly climbs with 1 in 28 gaining height in several spiral tunnels. The locomotive was constantly worked at full throttle and a cut-off of 45%. Superheat temperature reached 290° to 320°C, quite high, but managable for its slide valves. The photo shows the stylish train near Bergün. Picture taken by Georg Trüb
