In Current Cab Only mode, the function is activated by a throttle only if that throttle has selected this
particular locomotive. An example for using “current cab only” control would be a function such as the bell
or horn, as well as certain light functions such as ditch lights, which in real life is only activated by the lead
unit in a consist.
In Consist mode the function is activated by all throttles, independent of which locomotive is dialed on the
throttle. All functions influencing the motor or movement of the locomotives should be set to Consist mode,
such as Momentum, ABV, Brake, Brake Release, Rev Up/Down (Manual Notch Up/Down), etc.
By default, all function numbers are set to Consist mode except for Function 1 and Function 2, which are
assumed to be Bell and Horn/Whistle respectively.
4.4.2 Headlight MU switch
The MU Switch feature, available under the F0 submenu, is a unique feature of the TCS command station
which aims to add another layer of realism to consist control. This feature is based on real-life locomotive
operation, particularly in “modern” diesel locomotives. Depending on the configuration of this “switch”, the
lighting setup and control for F0F and F0R will change behind the scenes. The MU Switch feature has four
options to select from.
A) Solo Unit
Solo Unit is the default configuration, and makes no changes to the behavior and operation of the loco.
B) Coupled at Rear
Coupled at Rear means that this loco is an out-ward facing locomotive at either the front OR rear of the
consist, and is coupled to the rest of the consist or cars by its REAR coupler. In this mode, if F0 is ON, only
the “front” facing headlight will come on and the “rear” headlight facing the consist will remain off all the
time.
C) Coupled at Front
Coupled at Front means that this loco is an out-ward facing locomotive at either the front OR rear of the
consist, and is coupled to the rest of the consist or cars by its FRONT coupler. In this mode if F0 is ON, only
the “rear” facing headlight will come on and the “front” headlight facing the consist will remain off all the
time.
D) Middle Unit
Middle Unit means that this loco is somewhere in the middle of the consist, and is coupled to the rest of the
consist or cars by BOTH couplers. In this mode, neither the “front” or “rear” facing headlights will come on,
and will remain off all the time regardless of the status of Button 0.
4.5 Special Features of Headlight (F0)
For headlight, the Consist Behavior and MU switch options as described above are available in the Roster
Settings > F0 submenu.
4.5.1 Directional Control
Directional Control is a unique feature to the TCS command station. This option, which is disabled by
default, works behind the scenes to simulate the real-life headlight control of a locomotive without the need
to do CV programming to remap the headlights to different buttons. This feature is not exclusive to
