Steam engine Controls...

Technical Enquiry concerning Steam Engine Controls...

Does anyone here happen to know what the control layout on GWR Locos was?

This relates to something posted in another thread..

What loco in particular? - For a start GWR engines are right hand drive.

This could be of some little help maybe...

In specfic, this enquiry was posted in relation to the exterior of an 81xx series loco someone was making

Wot, me

As you're probably aware, the GWR went for a pretty extensive amount of standardisation.
Have a whole page on the cabs for the 41xx series (Nearly identical to the 81xx really, although this isn't really from the modellers perspective, and no full-on shot):

If you look at this photo (From a King, but the principles and locations are the same, rotations are from the top of my head mind, so may not be totally accurate):

• The large red handle in the centre is the regulator (Throttle). This swings from left to right to increase.
  
• The smaller red handle on the right is the reverser. IIRC this spins clockwise to full forwards, with reverse anti-clockwise, probably about 8-10 rotations either way.
  
• The small round brass circle thing with dots on is the brakes.
  
• The three handles at the top are injectors for adding water to the boiler.
  
• The tall rectangular gauge is the boiler water level
  
• The gauge top right is vaccum brake pressure
  
• The top left gauge is pressure
  
• Bottom left is steam heating
  
• Not sure what the bottom right should be, would have to look it up. Possibly air brake gauge.

Another page on the subject:

You'd really need to get to one of the existing 41xx locos for a proper look in the cab if you're thinking of modelling more than the basics.

I wasn;t aware you were already looking into this! - I lack the technical skills to actually code a plugin for 'steam' traction, and in any case I wasn;t sure the current physics model in OpenBve could cope with a full blown steam engine. (There are very accurate steam engine simulations around, but these don't have source code available.)

Hopefully this thread will encourage someone to write a 'steam' system plugin, (I think there was BVE 4 Plugin)

There are very accurate steam engine simulations around

What would they be? The best I ever saw was the steam locomotive simulator by Charl Vockerodt..

I was thinking of the one made by Bryan Atwell:=
