Depending on the model, the weight of a diesel locomotive ranges from around 100 tonnes to over 200 tonnes. GP38-2 locomotives weigh 125 tonnes, Dash 9 GE-C44-9W locomotives weigh 210 tonnes, C30-7 locomotives weigh 195 tonnes, and F7A locomotives weigh 104.4 tonnes.
General Motors’ EMD 710 locomotive has a six-foot-wide, 8.02-ton engine that can power about one thousand homes at peak performance. Modern diesel trains are equipped with diesel engines and energy generators. Unlike electric trains, this train is not connected to overhead wires. It generates around 35% of the power produced by an electric train of comparable weight.
