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
