11.0 Multiple Unit Operations
Digitrax command stations offers three methods of consist control:
1. Basic Consisting
2. Advanced Consisting
3. UniVersal Consisting (the Digitrax preferred method)
For complete information about these methods, please consult your
Digitrax Starter Set Manual.
By definition, Digitrax always adds loco addresses to the “TOP” loco
address in a consist.
The “TOP” loco is special, in that it is the address that receives the
speed & direction commands for the entire consist.
All non TOP loco addresses added to the consist are controlled by com-
mands sent to the “TOP” loco.
The TOP locomotive does not have to be a physical loco on the track, it
can be a phantom.
Digitrax defines the TOP loco as the loco on the R Throttle Knob at the
time when the MU add is performed.
All loco addresses in a consist will have the same status as the TOP
loco. They will all be common, in-use or idle based on the state of
the TOP loco.
Each loco within a consist maintains its original advanced 28/128 or
standard 14 speed step mode setting.
A consist can be released by one throttle and then selected and run by
any other throttle.
A consist TOP address can be dispatched and acquired on another throt-
tle just like any other address. See Section 14.0.
11.1 Adding a Locomotive To A Consist
Radio and Infrared throttles must be plugged in to LocoNet to add loco
addresses to consists.
To set up a consist using your DT400 throttle:
1. Select the loco address of the TOP loco on the R Throttle Knob.
2. Select the address of the loco you want to consist to the TOP loco on
the L Throttle Knob.
3. Move the two locomotives into position. The locomotives can be
headed in either direction. They can be adjacent to each other in the
