locomotive will push the cars of the train together when coupling. If this effect is not wanted, enter
0 for CV 146 which will stop the locomotive right away.
When using a PC-software, it is especially helpful to only allow a restart after a standstill if a newly
coupled wagon has already been logically joined to the train and the identification has been sucess-
fully completed. It is important to wait until this process is completed or else the locomotive will
not receive any uncoupling commands. If Bit 6 in CV 173 is set to 1, the locomotive will ignore
movement commands until the identification has been completed. A „0“ in Bit 6 CV 173 enables
the movement right after the uncoupling process has been completed.
How to uncouple vehicles automatically
The automatic uncoupling procedure proceeds fully automatically once the uncoupling command
has been acknowledged. If the locomotive is in standstill before the function key is pressed, the lo-
comotive will be automatically controlled(moved and stopped) through the decoder. If the locomo-
tive is moving while the function key is pressed, the selected speed step will be maintained. Before
activating the uncouling procedure, it is important to unburden the coupling by bringing the train
closer together and to activate the uncoupling procedure no sooner than 15 seconds after the cou-
pling has taken place respectively after the last uncoupling procedure in the train set. To automati-
cally unburden the coupling, CV 173 Bit 1 needs to be set to 1.
The following command sequence is sent via DCC-control centre e.g. in order to uncouple the sev-
enth car:

Set TCCS-address for T4T-train automa-

2
Set speed step for address 1218 to 7
This means that the following commands
are valid for the seventh car behindthe lo-

Acknowledge function key F1, When
changing the function status from 0 (OFF)
to 1 (ON), the command will be sent from
the locomotive-decoder to the decoder in
car 6 and 7.
With the control devices which allow an
impulse release these can be used accord-
ingly.
The couplings between the 6th and 7th car open up. Then the locomotive automatically moves away
(define speed through CV 144) from the activated car until the couplings are separated. After that
