Modernized snow ploughs in action

E-mail Print PDF

Between 2009 and 2015 Austrian Federal Railways (ÖBB) have modernized 23 snow ploughs to increase their reliability and improve the ecology. The old, oil-dripping plain bearings have all been replaced by new modern roller bearing wheelsets delivered by DLM. The special technology of these roller bearing wheelsets had been developed for the likewise modernization of the steam locomotive 52 8055. It allows the use of roller bearings without modification of the frame.

The heavy snowfalls in large parts of Austria gave the snowploughs a lot of work. Clearing the track by means of a snow plough is very attractive to look at, as can be verified by the short video:

New Boiler for Steam Ship SS Spiez

E-mail Print PDF

On December 1, 2018 the new boiler has been lifted into the boiler room of the screw steamer SS Spiez, see pictures taken by Robert Horlacher. The all-new two-cylinder steam engine is unfortunately not yet ready, which is mainly due to the generally excellent workload of the Swiss manufacturing industry. Tailor-made never meant priority within manufacturing proceses, but this time it was simply impossible to get things done in an acceptable time frame.
