Diesel Engine Selection on Locomotive Using AHP Methods

The paper presents selection of diesel engines for diesel hydraulic locomotives of 600 horsepower (478 kW). DHL 600 are locomotives intended for manoeuvring, towing cargo of up to 1000 tones, they are suitable for railways with no electrical contact grid, and due to their characteristics, they are classified as locomotives of medium strength intended for manoeuvring within railway stations and industrial terminals, forming and dismantling freight trains, as well as for towing lighter freight trains for shorter distances from the station where they are positioned for operating. DHL are primarily appointed for service within the railway station and belonging industrial terminals, and for towing lighter trains for shorter distances from the appointed station. The paper describes the selection of diesel engine using AHP method, based on economic criteria which have great influence on cost-effectiveness and financial feasibility.
