There are three operations shown.
The solid black lines show the volume and rpm operation of the diesel motor.
The dotted blue line with large dashes shows the volume and rpm of the Turbine Whine.
The dotted red line with small dashes shows the volume of the Turbine Whoosh.
The yellow boxes indicate major events in the transition to Turbine Mode. The timing shown in each box indicates the number of seconds since
the transition command was sent to start Turbine Mode.
Note:
Turbine fire is a distinctive sound that sounds like a giant gas furnace being ignited.
Changing from Turbine to Diesel Mode (F7)
There are two ways to return to Diesel Mode from Turbine Mode.
Press the horn button four times to produce four short horn hoots in Neutral.
Press the F7 key in Neutral.
The locomotive will go through a complex Turbine shut down scenario as depicted in the graph below. At the start of the transition to Diesel
Mode, the Mars Light will change from Dim to Off. When the transition scenario is completed, the Mars light will change from Off back to Dim.
