ZURICH, SWITZERLAND – A 4,000 ton annual reduction in CO2 and a significant improvement in maintenance costs: Swiss cargo trains will have 30 hybrid locomotives starting in 2013, the CFF rail company has announced.
The new engines are made by Stadler Winterthur, whose director, Hartmut Dietrich, calls them “the most modern and most innovative on the market”.
The locomotives were presented by the two companies 14 October in Winterthur.
The CFF’s traction energy consumption has remained relatively stable for the past four years, between 1,827 and 1,879 GWh.
The new engines are based on an existing model, entirely electric, used by the CFF for maneuvers with passenger trains, the Ee 922.
The new model’s (E 923) electric traction power is twice as great, but it also has a diesel motor for rail lines that have no electric contact points, which gives it far greater flexibility.
The new locomotives have a higher speed, up to 120kph, which will allow them to free the rail lines more quickly for other trains, resulting in sharply lower operating costs, says the CFF.
CFF is paying CHF88 million for the E 923 engines, some of which will be delivered in 2012, but it notes that it will lose the high maintenance cost of older locomotives, such as the Bm 4/4s, which are being retired.
