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):

Rhaetian Railway G 3/4 No. 11 "Heidi" back in Service after an extensive Overhaul

E-mail Print PDF

On Friday, July 11, 2014 the 2-6-0 tank engine G 3/4 No.11 successfully moved under its own steam following an extensive overhaul and modernization. This metre gauge locomotive was  built in 1902 by the Swiss Locomotive & Machine Works SLM in Winterthur. The rebuilding and modernization was a joint venture between the Swiss society of volonteers "Club 1889" and DLM Ltd. DLM delivered a new boiler including a superheater and the well known environmentally friendly  light oil firing system, new pistons and piston rods, new valves and valve rods and an electric preheating device.

This particular steam locomotive is  named "Heidi" since it appeared in the namesake Swiss film.

The electric preheating device can be seen in the lower left corner of the picture. It allows unattended, emmissionfree heating of the boiler overnight, up to a boiler pressure of 10 bar. Picture: Roger Waller

Fireless Technology for Ferrys

E-mail Print PDF

Up to now the fireless technology has only be used for shunting locomotives. Thanks to the enormous storage capacity of hot water under pressure, the simple and extremely reliable technology can be envisaged for other applications as well. Following the results of previous general study on behalf of the Swiss Department of Energy BFE, a detaild study for ferry operation on fireless steam will now be undertaken.
