Using Loco Functions

Pressing the numerical buttons on the keypad will operate the function 

assigned to that number on your locomotive. When a function is turned 

on, the function number will be displayed on the screen. 
To select higher function numbers than 9, press the Shift         button. 

The new function page selected will “persist.” You must press the 

Shift button again in order to continue through function pages. This 

was designed to allow for easy repeated operation of higher-number 

functions. On the left side of the screen, a small “1” or “2” will indicate 

that you are controlling higher functions: 1 for F10 - F19, or 2 for F20 - 

F28. 

Change Speed

When the command station is powered up, all locomotives will be set to 

speed zero, forward, with all functions off. To begin running a train, select 

a locomotive as described in the 

Select A Locomotive 

section. To adjust 

the speed of the active locomotive, rotate the knob clockwise to increase 

speed, and counter clockwise to decrease the speed. The throttle will 

always display 128 speed step mode but can still control locomotives 

operating in 28 speed step mode. Rotating the knob more quickly will 

change the speed more quickly.

Emergency Stop

The LT-50 has a unique 3-Stage Emergency Stop function. These three 

stages are described below:

Stage 1:

 Press the E-Stop button once to bring your current locomotive    

 

 to a stop.

Stage 2:

 Quickly press the E-Stop button again to stop all of the   

 

 

 locomotives on the layout.

Stage 3:

 Quickly press the E-Stop button a third time to turn track power   

 

 off completely.

When E-STOP is initially pressed, a small countdown timer will appear 

in the drive window. Pressing the E-STOP button again before the timer 

runs out will escalate the E-STOP to the next stage. To release any of 

these stages of E-STOP, wait until the countdown has finished and press 

the E-STOP button again. 

You can choose to enable or disable any of these three stages from be-

ing operable. For example, you may wish to use the E-STOP button for 

track power only. To configure this feature, navigate to:

 

        

Menu > Settings > Throttle Settings > E-Stop Settings
