The boiler and reciprocating expander (engine) ran at a steam pressure of 1600 PSI and a superheated steam temperature of 1600 deg-F - both much higher than anything ever contemplated in a steam locomotive. The high temperature was needed for thermal efficiency (fuel economy) and the high pressure allowed the engine to be compact.

Could you explain further where your 1600 degrees F is used?
Boiler produced superheated steam at 1600 deg-F, 1600 psi. This was the working fluid supplied to the reciprocating expander which admitted steam through sequential poppet valves and exhausted through ports into a condenser. I did thermodynamic analysis but not metallurgy... Ceramic pistons and cylinder liners were considered as a means of further increasing efficiency.

What was the material of the steam generator? What material transferred the steam from the generator to the pistons? What volume?
I think the boiler was stainless steel but not certain. Bore and stroke were approximately 3-inches each with 4 cylinders.
