In this paper, hybridizing a heavy vehicle is developed. A switcher locomotive is considered for hybridization. Due to their
low operational speed, the switcher locomotives require much lower power when compared to other types of locomotives.
Besides, switcher locomotives have higher loss of energy due to their frequent starting and stopping. Hybridpowered
transit vehicles are considered to be excellent replacements for ordinary transit vehicles, since hybrid powered
vehicles are equipped with more than one traction power sources. Therefore, a switcher locomotive’s driving cycle is
derived from the measured field data and used to calculate and design the hybrid vehicle’s components. A ‘‘fuzzy
controller’’ is used to plan a suitable controller for the designed hybrid locomotive. Comparisons show a substantial
decrease, both in the fuel consumption and the pollutions of the designed hybrid switcher locomotive versus the
conventional diesel-electric locomotives.
