How many kilometers can a locomotive run on a full tank of fuel?

[LaJameson]

How many kilometers a diesel locomotive can run on a full tank of fuel is a variable number, influenced by multiple factors. 1. It depends on the track conditions (curves, gradients, etc.): Smaller curve radii result in greater energy loss, leading to higher fuel consumption and reduced running distance. Similarly, if the track has steep gradients or is a mountainous railway with frequent ascents and descents, fuel consumption will be significantly higher compared to flat terrain. 2. It depends on the tonnage hauled: The fuel required to pull a 1,000-ton passenger train is certainly different from that needed for a 5,000-ton freight train, and the running distance will also vary. 3. It depends on the operating speed: Fuel consumption differs when running at 160 km/h compared to 100 km/h. 4. Other factors: For example, fuel consumption is higher in cold weather than in summer, and at high altitudes, the lower oxygen concentration in the air increases fuel consumption, among other factors.
