The first hybrid railway vehicles – Impuls 2 – are already on the move. Manufactured by NEWAG for the West Pomeranian Voivodeship and equipped with Medcom’s state-of-the-art propulsion systems, they have been running along the non-electrified railway line between Szczecin and Kołobrzeg, among others, since January.
Impuls 2 is the first hybrid vehicle manufactured in Poland to boast a two-drive system. Just like any other train, it may function and move as an electric train (powered by electricity with the use of a pantograph). What makes it stand out, however, is the fact that on sections of the route without access to the traction network, it switches to the diesel mode. The two-drive system will work great in all those places where local governments – just like in West Pomerania – want to revive regional communications and intensify traffic on non-electrified routes.
The two-drive system comprises two traction containers intended for controlling the operation of asynchronous traction motors and generating voltage of the vehicle’s on-board systems. Moreover, the vehicle was equipped with traction inverters, auxiliary converters, battery chargers, the train control and monitoring system (TCMS), and low-voltage power distribution units manufactured by the Warsaw company.
Another six Impuls 2 hybrid vehicles from Newag were ordered by Lower Silesian Railways (Koleje Dolnośląskie).
