ECOLOGICAL SOLUTIONS FOR FREIGHT TRAINS

Popis výsledku v původním jazyce

The article presents the potential of freight railway transport in terms of saving ofemissions and maximizing the efficiency of operation. Attention is paid to the transport of freighttrains on electrified lines with higher gradients (up to 25permille), alternatively with the possibility of a tripto non-electrified lines and sidings, which generate significant extra costs in the operation of trains andare often a reason for the carrier to deploy a locomotive of independent traction (diesel-electric) even inelectrified line sections, even at the cost of increased operating costs and increased emissions. There aremany such lines and possibilities of use within the Central European region and the Czech Republic.In the first part of the article, the basic categorisation of dual-mode freight locomotives and theirsuitability for individual operating programmes is presented. This part also describes current situationon the rolling stock market in general and directions of development taken by various locomotivemanufacturers.Case studies of deployment of real freight locomotives on chosen Czech railway lines are usedin the next part to present the possibilities for energy and cost savings when replacing a vehiclewith independent traction by an electric or dual-mode locomotive, at least in sections equipped withoverhead catenary. The pros and cons of using several possible solutions are described in detail. Furtherconsiderable savings can be achieved by, among other things, using regenerative braking and returningthe generated electricity back to the catenary system when driving downhill. In this respect, however,it is also necessary to cooperate with the infrastructure manager, who must also adapt the railway linesto the operation of these vehicles.Finally, general rules for operational deployments on which the replacement of a conventionalvehicle by a dual or pure electric vehicle can be considered are formulated.
