The common sources of energy for heat engines have been wood, coal, and petroleum products. These carbon based fuels combine with oxygen at a sufficient temperature for a continuous release of heat. In the railroading scheme of things this heat is then converted to mechanical energy to provide locomotion. Since the system for this activity is self-contained, adequate carriage must be provided for the conversion mechanism and the fuel for a reasonable distance of travel. Provisions must be made along the route for replenishment.
