Step by Step to Fossil-Free Track Work Machinery

Track construction work requires track-work machines - and these are currently largely diesel-powered. TU Graz investigated fossil-free drive alternatives for the special construction machines. Image source: Lunghammer - TU Graz By Susanne Filzwieser Rail infrastructure is currently largely built and maintained using diesel-powered track-work machinery. Together with partners, TU Graz is investigating alternative drives for special machinery. For safe railway operation, tracks must be regularly maintained and renewed. This requires special construction machinery, most of which is nowadays powered by diesel engines. Particularly large track-work machine groups with a length of several hundred metres require up to 1000 litres of diesel per kilometre of track laid and renewed.
