Dampers:  The dampers are the primary control of airflow to the firebox, and therefore the amount of
heat given off by the fire. Open the damper doors to add air and increase heat; close the damper
doors to reduce air and lower the heat level. You may end up leaving the damper doors open for the
entire journey.
Blower: The blower keeps exhaust gases moving through the exhaust stack, causing a vacuum that
draws air through the firebox. Use the blower when there is not sufficient natural draft flowing
through the firebox to keep the fire hot. This might occur when the locomotive is standing, coasting,
or under very low power. You can also turn on the blower to raise steam quickly, since the increased
airflow helps the fire burn hotter and makes the combustion more efficient.
Firebox Doors: Open the firebox door when you need to add coal to the firebox, or when you need a
secondary air source for the fire. Opening the firebox door is not as effective as opening the dampers
in making a hotter fire, but can be helpful for adding some extra oxygen.
Shovel and Firebox: Add the proper amount of coal to the firebox to keep the fire at the desired heat
level. There is an art to adding coal to the fire in the right amounts and at the right times. Too much
coal on the fire may suffocate the fire; too little coal will not produce enough heat to raise steam.
Remember to add coal and allow the fire to heat up before injecting additional water into the boiler,
since adding cool water also has a cooling effect. Also note that it’s bad form to add coal to the
firebox when in a station; it produces too much smoke.
To manage the fire well you need to be familiar with the locomotive and plan ahead by at least 10
minutes. On the Scotsman, planning 20 to 25 minutes ahead is a good idea.
Boiler Water Gauge: The Boiler Water Gauge shows the water level in the boiler. The level shown is
affected by circumstances that can cause the water level to shift, such as a grade or changes in
speed.
Injectors: Because the water in the boiler is constantly being converted to steam to power the train,
injectors are used to
 
move water from the tender into the boiler. Because the injectors use steam to
move the water, and because cool water from the tender cools the water in the boiler, try to plan
ahead so that you don’t need to use the injectors when the locomotive needs a lot of steam power to
move the train.
On mainline locomotives such as 
Flying Scotsman
, it is common to leave one injector on most of the
time and use the second as required. The locomotives are designed with this in mind. Under medium
power demands, one injector should be enough.
Tender Water Gauge: The Tender Water Gauge indicates the water level in the tender. If the water
level is low, refill the tender’s water supply at a water tower. In the real world, the Tender Water Gauge
is located on the tender, but in Train Simulator it is located on the front cab panel, next to the Boiler
Water Gauge.
Water Scoop: The Water Scoop is used to add water to the tender when passing over water troughs
placed between the rails.
