Here we observe that the stoker is the only thing causing steam consumption. Maybe this is correct, but in reality the blower is activated when idling, something the AI fireman does not take into account (also true for safety valves)...
Here, about 10 minutes later the amount of coal in the tender is still the same, which is wrong as the water needs a constant flow of energy to stay evaporated, independent of fuel calorific values which I may have to test. I have´nt driven oil-fired steamers for a while because of this.
Regarding the burn rate curve that has no influnce upon the fuel quantity value. Also where we can get the values from?
Regarding boiler lagging; yes I tested those lines but to no avail.

BTW: Just to clarify what I mean by "The Stoker should not be used while idling", I have highlihgted the following quotes from the 1944 firing guide:

Things in progress
- New Smoke
- Sparks/burning embers
- Steam Locomotive Per Axle Wheel Radius (many steam locomotives have different sized wheel on different trucks - sometimes on the same truck)
Future
- Chuffing/synchronized sound
- Reverser Animation
What needs to be fixed/Updated with Coding
- BTU
- Coal and Water consumption
- Stoker/Hand Fired
- Working Blower
- Factor of Adhesion
- Steam Locomotive Wheel Slip Animation Needs to be Retarded to Behave More Prototypical-
- Blow down for both sides of locomotive simultaneously
- Feed Water Heaters/injectors
- Updated Fire Modeling Physics
Eventually would like coded
- Working boosters
- Steam and smoke effected by cold or weather
- More then one whistle/Horn button
- More Light Switches to Accommodate Class Lights.
If anyone else can think of more please feel free to add.

Don't forget oil firing! Not sure if that counts with "Updated Fire Modeling Physics"...

Oil-firing is mo different from coal or wood firing except of cource higher energy content and also mechanical assistance to get it into the firebox; this is one case where is 'stoker' really needs to run all the time.
And don´t forget better definition of wheel arrangement/diameter.

Hi Brandon,
The curse of the perfect fireman.
;)
Go to manual firing and they blow off immediately.

Oil firing has some significant differences from coal or wood firing. Most importantly for the OR model the boiler response is much faster - when you increase the oil supply more heat is immediately available, whereas if you shovel on more coal then the heat is not available to the boiler until the coal has burned through. The reverse applies when you stop firing. (A bit like the difference of cooking with gas and cooking with electricity.)

This one is a bit naughty. If you study the figures in the extended HuD the safety valves should go off sometimes with the AI fireman.
There are numbers there for stored energy and max energy - if stored energy exceeds max energy the boiler should blow off.
With the AI fireman the safety valves are actually locked - you can watch stored energy rise above max energy at times - but the boiler just takes it without either the pressure rising above the max boiler pressure or the safety valves lifting. (Compare that to manual firing.)
I think you can kill this feature by switching to manual and then back again. You can also kill it with the start and stop firing commands.
That brings into question the behaviour of the safety valves - I am not sure it is realistic - as Coronavirus restrictions in UK are going to keep me away from steam loco footplates for some time to come, I will not be able to observe in person. So I would like to discuss this with anyone who has fired a real loco. Do we have any actual firemen on this thread?
