Steam Heating Instructions

Post by darwins » Tue Dec 31, 2019 9:07 am

Does anyone have to hand a copy of the LNER instructions regarding steam heating?

LMS instructions were to use 50 psi for the first half hour of journey for main line trains and then 30 psi for remainder of journey. (For local trains 30 psi throughout.)

Instructions on GWR steam heat pressure gauges suggest they used up to 80 psi depending on train length

I have a copy of the LNER General Appendix dated 1st Oct 1947.

It says:-

The pressure regulator must be set at 60 psi in the case of Pacific, Atlantic and the larger 4-6-0, 2-6-2, 2-6-0 and 4-4-0 engines, and 40 psi on all other
engines except in the Scottish Area where the pressure on engines , other than those specified above, must be 50 psi.
