High-pressure locomotive work at the steam pressure of
Right Answer is:
20 – 30 kg/cm2
A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. In the later years of steam, boiler pressures were typically 200 to 250 psi (14kg/cm2 to 17 kg/cm2). High-pressure locomotives can be considered to start at 350 psi (24.11 kg/cm2).
