The blower on steam locomotives has long been inoperative when in autofireman mode in OR. This is actually contrary to MSTS where it was active and had to be used when entering tunnels to prevent exhaust blowback. It was also used to increase or maintain fire heat when required such as standing at signals etc. Can we have it working in OR please. Can we also investigate the possibility of adding blowback.

Hi...

Concur - wasn't this something that came up when we were discussing the actual fire needed to be modeled better as well ? Maintaining the fire in MSTS took real effort.

There is some information on the development of the blower in UK.

In manual firing mode it seems to have far too much power over the boiler.

Adding in auto-fireman mode is a complex beast - as so far OR does not do opening the fire doors, shovelling coal on, controlling the secondary air flow... If the fire box doors are always shut then there is no blowback anyway.

Then we would need some input I think from experienced firemen. I believe blowback or not might depend on many factors interacting - how hard the engine is working = blast - blower setting - fire box door opening - front and back damper setting - size of tunnel bore - trains coming the other way... ???

Blowback was always a possibility as firehole doors were never an airtight fit.
