20-year anniversary of DLM

28 August 2020

Dampflokomotiv- und Maschinenfabrik DLM AG celebrated its 20th anniversary on 29 August this year. The company history is summarized in the chapter "about us".

When the Na-class steam locomotive 14A of the Australian Puffing Billy Railway had been converted to oil firing, much progress has been made regarding the elimination of the occasional "rumbling" noises. These findings have now been applied to the oill firing of "Heidi". Before this little conversion it was possible but rather tricky to avoid the rambling.
