Czech rolling stock manufacturer, CZ LOKO has presented the EffiShunter 3000 electric shunting locomotive at the Czech Raildays event in Ostrava. The two system, four-axle EffiLiner 3000 is designed for long-distance freight train shunting on 3kV DC and 25kV AC power networks of the Czech Republic and other 1 435mm gauge European countries.
Under CZ LOKO’s leadership, over 10 Czech and Slovak railway companies, primarily ACRI members, participated in this project, which began three years ago, and has now reached its final stage. Initially, in April 2013, an obsolete Class12 electric locomotive was imported from the Belgian state transporter, SNCB, in order to be entirely modernised. Another 11 vehicles of the same class, all of which have been transported to the Czech Republic, will also be modernised.
Due to the EffiLiner project, the CZ LOKO Company has expanded its production programme, based initially on deisel-electric locomotives and special vehicles, by progressing into a further segment of modernisation. “We can now provide railway operators with the optimal solution for freight transport with independent electric traction, including complete after-purchase service,” explains Jaroslav Plhak, CZ LOKO’s Sales Director.
While modernising this locomotive, emphasis was put on improving original parameters, high reliability, low operational and maintenance costs, environment-friendly operation, safety, modern design, and utilising unified solutions. Its continuous power are constant for both power circuits, and that being 2 910 kW. The maximum speed was decreased from 160 to 120 km/h, as this locomotive is intended for freight transport. Its total weight of 85 tonnes remains the same.
The complete bogies including traction motors and the hoods are all original. All other parts have been designed and constructed in accordance to current European standards.
This modernised locomotive is newly fit with EVPU traction transformer and traction equipment, GINO ESE brake resistors including, of course, dynamic brake usage with a recuperation function, Alfa Union vaccuum alternating switch, Secheron direct current switch, MSV Elektronika superior control system, as well as anit-skid and anti-slip devices to protect the wheelsets, and new cabling in accordance with current norms. All auxiliary drives are now driven by asychronnous motors. The Oerlikon air brakes have completely been replaced with the new DAKO system.
