"He explained how the reserve of energy represented by the steam pressure in the boiler provided for any occasional overload which would defeat a standard internal combustion engine of the same power.[1] Independent heating of the boiler was occasionally used, to provide extra power for exceptional conditions, and in the first stage of operation to allow the engine to start itself from steam power alone, even against a load."

"The cylinders were made double-ended, with the rod end of each cylinder for steam and the closed end fitted with a diesel injector" "The sequence of operation was to heat the boiler in the normal way, but using fuel oil instead of coal. The start from rest would be made with steam power, but at about five mph (8 km/h) the diesel injectors would be started and the steam turned off. The waste heat from the cylinder jackets and diesel exhaust then maintained the boiler in steam for auxiliary functions (brakes and whistle) and in readiness to supplement the diesel power if required, or for the next start" (link)
