Investigation of hybrid locomotive options for mixed freight and inter-modal trains

The hybridisation potential of several different train systems, in particular; (1) A small container train, (2) A novel container train (e.g. Cargo Sprinter) (3) A road trailer handling train (e.g. Iron Highway) was analysed using train simulation and compared to heavy haul systems. Train simulation was used to evaluate train performance over a 50km trip length. The simulation was controlled by a rule based algorithm that sensed approaching speed restrictions and grades. The same algorithm parameters were used for all train types. The results showed that the potential for improving energy efficiency was similar for both a typical heavy haul track and an undulating track. Only loaded trains were compared. The Cargo Sprinter showed the highest potential for hybridisation, whilst the worst energy results were associated with the Iron Highway.
