During the run
First of all keep an eye on the track and the signal aspects.
Keep also monitoring the water level regularly.
During the run, keep the water level up. A departure will use a lot of water and steam.
Do not inject water until the run becomes stable.
This is also the reason to top the water up when the boiler is in state of “rest”.
Press [ K ] to open the water feed of the exhaust injector. (Press Shift – [ K ] to close)
Press [ I ] to open the exhaust steam feed.
Press [ I ] once again to close the steam feed when ready
Do not use two injectors at the same time as mentioned before. This will cause a steam pressure drop unless it is necessary due to some tremendous drop of water level in the boiler.
During the run, use the Exhaust injector. When stopped, use the live injector.
Prevent the drop of water level less than 70%.
Less water will result in unnecessary usage of steam.
The evaporation surface will increase on the decreasing of the water level which causes more stoking in order to keep up the water level. You need to inject more causing steam usage which is resulting in a increasing rate of coal consuming. You then need more coal to keep up the pressure.
This is why you have to keep up your fire and water level
Easy to remeber: Keep tehe water level above 75%
An exception is the Challenger and Big Boy. Keep the water level above 96%. The amount of water use is tremendous. To keep the water evaporation surface as small as possible, it is necessary to keep the water level as high as possible.
Within TS20xx it is not possible to stoke in a donut shape fire though it is good to keep it in mind the way of shovelling will affect the volume on certain spots at the firegrate. In practice: Do not shovel coal just on a great heap on the fire grate bus spread out equally as a donut shape fire with less coal in the middle and a high volume of coal just underneath the firedoor.
The stoking sequence:
Stoke 8-10 shovels at about 10 kg of coal per shovel you throw.
Inject water (Exhaust steam)
Additional Inject water (Live steam) only at low water level.
Check steam chest pressure when driving.
Check brake pressures.
Adjust the use of the small ejector
Check water level.
