Until now, track maintenance machines have used internal combustion engines for running and working. Diesel engines drive the machines during transfer travel and provide the hydraulic pressure for working at the worksite. This leads to CO₂ emissions, causes noise, and is problematic during construction work in tunnels and in densely populated areas.
The alternative: green current from the overhead contact line powers electric drives. This applies to the drive, but also to the work units, which are converted from hydraulic to electric.
The use of electric current as an energy source reduces local CO₂ emissions to zero and makes operation significantly more energy-efficient.
Plasser & Theurer offers eco-retrofits with electric tamping units for existing fleets. They reduce the rotational speed of diesel engines, decreasing fuel consumption in existing fleets.
Machines for the construction and maintenance of the overhead contact line cannot be supplied via the contact wire during working. They have batteries that supply power for an entire shift. They are charged during transfer travel via the overhead contact line, via recuperation, and there is a power pack as a backup.
Internal combustion engines are still the standard in many areas. Plasser & Theurer is focusing on alternative, climate-neutral fuels. Possible applications for fuel cells and hydrogen are also being researched. However, they will only become relevant for railway construction and maintenance in the future.
