High-pressure locomotive work at the steam pressure of

### Right Answer is:

20 – 30 kg/cm^{2}

#### SOLUTION

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/cm^{2} to 17 kg/cm^{2}). High-pressure locomotives can be considered to start at 350 psi (24.11 kg/cm^{2}).
