High-pressure steam locomotive - Wikipedia

A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal for other locomotives. In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa). High-pressure locomotives can be considered to start at 350 psi (2.41 MPa), when

Steam pressures and temperatures in current practice have reached 97–164 bar and 480–565°C or 593°C. The rate of increase in efficiency with increase in pressure becomes less as the pressure increases. A limit to the practicable operating pressure is set by the difficulty in separating moisture from steam in the boiler drum.
