Hello
Happy to be corrected but I so far understand that there is a BR publication numbers 33056 which is Train Crew Manuals or Working Instructions which, it seems, contains sections for all rolling stock.
I'm completing some research into the Class 37 and 73 and wondered if anyone had copies of the relevant 33056 sections that they would be willing to lend me for copying (I appreciate that's a tall order to ask) or instead copy/scan for me (happy to pay for this and your time) relating to the Class 37 and 73?
I not sure how much detail or length these documents go into but I'm primarily interested in understanding more about how the power lever is setup and the system to signal to the engine the lever position etc in both these types. I believe that was all via air pressure signals to the engine governor.
In parallel and if anyone has information on this too that would be great to hear from you, I believe the early Class 37s had a non-notched power lever whereas later ones received a mechanism on the power lever that cause it to have distinct notches. The engine setput, air signals etc were the same for all types, it's just this change of having a mechanism on the lever to make it have distinct steps.
Does anyone know the locomotive number from which this change in the power lever setup was from? I suppose it would be as a reference to the Dxxxx number rather than 37xxx.
For a Class 37 with notches, how many are there?
Similar questions for the Class 73 in diesel mode. Does it have a continuous movement power lever or notches? If notches, how many?
Does anyone have any information on the engine power per notch for these two locomotives too?
thanks all!
Casper
