For the first time, our E³ hybrid drive system powers a continuous action turnout tamping machine. Krebs Gleisbau AG and Swiss Railways have already set store by the new machine.
The new E³ hybrid drive concept allows the machine to be powered either via a diesel engine or via an electric motor using the electrical energy of the contact wire. Both engines generate the hydraulic pressure required for all systems, from the hydrostatic drive for transfer travel and work travel to the work units. The first two machines fitted with the E³ hybrid drive system – a 09-4X E³ Dynamic Tamping Express and a BDS 2000 E³ – have stood the test in regular work site operation in Austria.
Advantages of multi-sleeper tamping
However, continuously working MULTI-sleeper tamping machines show their full potential not only in short track possessions during maintenance tamping. Machines in the X series also offer advantages when laying new track, for example, following extensive track rehabilitation. They are designed for high lifting and lining forces. As lifts take place in multiple work stages, this also means the machine’s increased output allows you to complete construction noticeably faster.
For quality reasons: MULTI-sleeper tamping units provide more uniform working action, which translates into higher maintenance quality. Owing to a longer frame, bending stress of the rails decreases. And the subframe bogie that fixes it in place prevents elastic rebound of the track after tamping, lining, and lifting.

Quality cuts costs: our machines turn a tidy profit
To date, Plasser & Theurer has supplied 17,000 machines. Most of them are still in operation. This attests to the quality of the machines and the value of our Customer Services’ life-long machine and fleet support. Plus, it proves that high quality ensures high cost-efficiency: machines that have been in operation for 20 or 30 years paid off years ago.
Economic – Ecologic – Ergonomic
The latest track maintenance machines use both the electrical energy from the contact wire and batteries to power the working drive. Our new E³ drive technologies reduce local emissions - of both pollutants and noise – to a minimum on the work site. Introduced in 2015, Plasser & Theurer’s E³ machines stand for: Economic – Ecologic – Ergonomic.
