Blow the Whistle

Engineers are required to blow various whistle signals to warn of the approaching train as well as notify both passengers and train crew to the planned movement of the locomotive. Some of these are signals for grade crossings, stopping, moving forward, backing up and more.

Whistle Signals


  • = Short Blast

  • = Long Blast

  • ——

    Approaching Grade Crossing. (Hold final blast until crossing

is reached.)

  • Approaching a bridge or tunnel

  • Stop, set brakes

  • ——

    Release brakes and proceed forward

  • 


  • 

    Request signal from Trainman

  • Warning whistle, used when approaching points where

view is obstructed.

Learning and using the various whistle signals can add a lot of fun to your operating sessions! Some of the more common signals are indicated here. To activate the Whistle, press F2 on your cab: the longer you press the key, the longer the whistle will blow. While this allows you to make short or long signals, F3 is designated as a ‘short’ whistle so your shorts will have that nice, crisp, ‘toot’ regardless of how responsive your cab controls are…try a grade crossing whistle!

Blow Down the Boiler

If your steam engine’s been sitting in the station awhile, there’s bound to be some particle buildup in the boiler. Press the F4 key to open the blowdown valve and blow out the sediment. Press the F4 key again to close the blowdown valve.

Automatic Steam Sound Functions

Some sound effects happen in response to an action other than pressing a function key. The blowers will automatically simmer in the background to help vent the steam and keep up a good draft.

Airpumps Brakes on trains operate using air pressure. When the engineer activates the brakes, he is releasing air pressure, forcing the brake shoes against the wheels and causing the train to slow down. When the engine stops the air pressure is build up using a compressor, also called an airpump. The air pumps will pound out a steadily slowing cadence that simulates the build up of air pressure in the main reservoir. Deceleration of the locomotive while applying the brakes will cause the air pump to resume pumping.
