Sec. 230.23  Responsibility for general construction and safe working 

pressure.





    The steam locomotive owner and operator are responsible for the 

general design and construction of the steam locomotive boilers under 

their control. The steam locomotive owner shall establish the safe 

working pressure for each steam locomotive boiler, after giving full 

consideration to the general design, workmanship, age, and overall 

condition of the complete boiler unit. The condition of the boiler unit 

shall be determined by, among other factors, the minimum thickness of 

the shell plates, the lowest tensile strength of the plates, the 

efficiency of the longitudinal joint, the inside diameter of the course, 

and the maximum allowable stress value allowed. The steam locomotive 

operator shall not place the steam locomotive in service before ensuring 

that the steam locomotive's safe working pressure has been established.
