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

E-mail Print PDF


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

Commissioning and staff training was continued on April 6 and 8, 2015, successfully working trains out of Samedan to Pontresina, St. Moritz and Bever. The new technology is entirely hidden, so that the outer appearence is exactly what it was back in 1902. The engine doesn't smoke though. Even at full power the combustion of the light fuel oil firing is clean. Most important is the prevention of lineside fires.  Photo: Armin Brüngger

E-mail Print PDF

Following the recent delivery of further roller bearing axles by DLM, the  modernization of all 22 snow ploughs is now complete. As can be seen in the picture, the snow ploughs are being pushed by electric or thermal locomotives. The clearing of tracks and platforms (see picture) is fast and efficient. Tracks can be ploughed with up to 60 km/h and for transfers 80 km/h are allowed. The first snow plough on roller bearings has been commissioned on December 21 in 2009. Please also read "Further Application of 52 8055's Technology" below.

Further Application of 52 8055's Technology

E-mail Print PDF

The Austrian Federal Railways  have placed another order for the delivery of further sets of roller bearing axles to modernize the remaining snow ploughs previously equipped with plain bearings. The production is already in process.

The first delivery of roller bearing axles dates back to 2009. "Your product is fantastic, we had no repairs". Quite contrary to the previous plain bearings, which caused a lot of trouble. This special solution for roller bearings fitting in the existing frames had been developped for 52 8055. The total of these roller bearing axles amounts now to 97. For pictures and further information please see the previous news chapters dated September 11, 2009 and March 29, 2010.

Technology and history of the modern 52 8055 are described in a chapter of the all-new German book  "Die Baurehe 52.80"  (pages 73 bis 81):
