I will have 30 minutes of run time with this engine (light) on some yard trackage.
She has a manual reverse quadrant, manual lapping independent brake, and one injector on the fireman's side.
I have run both Ex-SR 630 and 722 about 25 years ago, and still have my operating manual complete with notes on ABD brake valves and associated systems.
TVRM based our rules on the SR rule book, which I also have an amended copy in my bookcase.
Operators of #75 receive a certificate and a hat for their participation.
Will report back to the forum after my throttle time on Sunday, June 1st.
