SWISS Federal Railways is fitting the cab air-conditioning of 114 locos with seven VS-606V7 AC inverters supplied by Yaskawa Electric in a €150000 order.

As well as withstanding the mechanical stress from the vibrations of a moving train, the 4 kW inverters were initially tested on two locos to ensure there would be no problems with condensing water as trains pass from freezing winter temperatures to the relatively stable warmer temperatures in Switzerland’s long Alpine tunnels.
