Your DCS50 uses universal consisting so that MU operations are simple and
easy to do. This is the most flexible and realistic method of MU’ing available.
You can add any locomotive to your MU, no mather what kind of DCC
decoder is in your loco. You can even add an analog loco to your MU. You can
add a locomotive to an MU in either orientation and in any physical location in
the train. When you send commands to the MU you use the address of the TOP
locomotive to control the entire MU and the command station handles the rest
of the commands to the other locomotives in the MU. Since the address you
will use to control the consist is not necessarily the address of the lead or head
end loco, we use the term “TOP” locomotive for this special address. The TOP
locomotive address can also be the train number.
You will not be able change the speed or direction of any individual loco that is
part of an MU. Locomotive speed and direction for all locos in the MU are
controlled by the TOP locomotive address.
17.1 Adding a Locomotive To An MU
To MU two addresses together with the DCS50:
1. Choose two locos you want to MU together. Place them on the track.
Make sure that both locos that will be part of the MU are headed in
the same physical direction. Select and run the first loco and run it to
determine which way it is headed. Then select the other loco and run
it in the same physical direction.
2. Select the loco address of the loco you want to use to control the MU.
This is called the TOP loco. To do this, press LOCO, enter the
address & press LOCO again. For this example, we will use loco
address 09 as the TOP locomotive and we will add address 23 to the
MU.
3. Press the MU key. The address of the TOP loco will remain in the dis-
play and the MU Indicator Dot will begin blinking indicating that
you are preparing to add to the MU.
4. Use the numeric keypad to enter the loco address you want to add to
the MU, in this case 23.
5. Press the + Key. If the MU you just set up is valid, the display will
