Engine Shutdown Timer (E.S.T.)

The Engine Shutdown Timer (EST) is a simple timing device, designed to shut down the engine after it has spent a certain amount of time in idle.  

This timeframe can be set to 15, 30, 45, or 60 minutes, according to your preferences.

After main engine is shut down, the EST will wait 2 minutes before turning engine lights off. 

Designed for applications where the main locomotive is supported by an APU, the EST works with the APU to avoid waste of the main engine’s power.  This is accomplished by shutting down the main engine and allowing the APU to monitor functions. 

EST Main Panel and Display Panel

The EST consists of a Main Panel and a Display Panel. 
The display panel has two buttons, APU START and HDLT (Headlight) RESET.

APU START is for conveniently starting the APU from the cab of the main engine.
HDLT RESET is a timer that will count down while the main engine is in idle, during the last 30 seconds of which, the beeper will sound.

The beeper will also sound 5 short times if the APU START button is pressed and there is a problem starting the APU.
