Tognum to supply more than 200 rail drive units to Alstom

  • Environmentally friendly underfloor diesel drives for Coradia Lint regional trains
  • Fuel-efficient operation with “Traction Powerpacks”

Tognum is to supply a total of 206 MTU-brand Powerpacks to railcar manufacturer Alstom from 2012. Alstom will install the underfloor diesel units in 56 regional trains which will go into service with Deutsche Bahn in the Greater Cologne and Eifel region, known as the Cologne Diesel Network, from December 2013. The drive units meet EU Stage IIIB emissions regulations which come into force in 2012. The new Coradia Lint 54 and 81-type trains are Deutsche Bahn’s first diesel multiple units to be fitted with SCR catalyzers for exhaust gas cleaning and nitrogen oxide emissions reduction. In addition, in-engine technology will reduce particulate emissions by around 90 percent. In conjunction with an innovative engine management system, the new technology reduces diesel fuel consumption and therefore CO2 emissions by up to five percent.

The Powerpacks with 390 kW diesel engines of the type 6H 1800 R85L are scheduled for delivery between March 2012 and September 2013. The two-car Coradia Lint 54 vehicles will each be fitted with three Powerpacks whilst the three-car Coradia Lint 81 versions will get four Powerpacks each. On each vehicle, one of the three (or four) Powerpacks can be shut down to achieve significant savings on fuel and operating costs depending on the route involved. The units, also known as “Traction Powerpacks”, will be supplied in a cost-efficient configuration without assemblies such as on-board power gensets or aircon compressors. As an operator, Deutsche Bahn also benefits from the opportunity to precisely tailor the package supplied to the service operated. Consistent savings on diesel fuel mean increased costefficiency over the entire life of the vehicles.
