WD-PWxxx and the T4T Train Automation (TCCS)
The decoders of the LD-1x and WD-xxx familys are the central access to the extended functions of
the T4T train automation. Further requirements for the use of T4T train automation are:
The use of the H0-vehicle coupling TC-H0 for vehicles with coupler pockets in accordance
with NEM-362
The use of the LD-1x locomotive-decoders
The use of the WD-xxx car-decoders
The use of a DCC-compliant control centre (if in doubt, contact us)
The core of TCCS is the production of a 2-pole connection via the TC-H0 coupling which can cou-
ple all LD-1x and WD-xxx decoders with each other. Via this link the decoder of the locomotive
(LD-1x) automatically detects how manyvehicles are in a train set and in which order.

The decod-
ers can also automatically determine whether the vehicles are on the driver's cab end 1 or 2. The
locomotive-decoder recognizes whether one car or multiple cars have been coupled, whether a
shunting locomotive has been coupled in order to uncouple a through-coach, etc.
Once the identification of the train set, i.e. after the automatic detection of how many cars and/or
locomotives have been integrated into the train set and at which position, the desired car functions
such as uncoupling, lighting, opening / closing doors, etc. can be activated via the DCC-control
centre.
The detected order within a train set remains intact even when the model train has been switched
off. Should the order within this train set be changed manually or a car should be taken out of or
added to this train set after e.g. derailing, the detection needs to be triggered manually. Function key
F7 (depending on the CV 201 to 212 settings) has to be switched from "OFF" to "ON" once.
All T4T-train automation functions or commands are sent to the locomotive. Every locomotive is
assigned a second DCC-address either as primary or as extended address (see CV 170 ff). This sec-
ond DCC-address is the TCCS-address. This can be organized either automatically or manually, as
shown in the following example:
I.
A Diesel locomotive type 218 is controlled via the DCC-extended address 218 (CV 17 = 192
& CV 18 = 218, CV29 Bit 5 = 1)
II.
For the extended T4T-train automation functions, the Diesel locomotive receives the DCC-
extended address 1218 (CV 170 = 1). As a consequence, the control center transmits 28 or
128 speed steps for this address!
If this address is entered on the control center in accordance with II), the speed step will be regarded
as a car-number. Speed steps 0 through 50 are supported. If speed step 1 is selected in the TCCS-
address for the T4T-train automation (in the example given 1218), all functions that are triggered
via this address (always when switching from „OFF“ to „ON“), will be interpreted as a command
2
This TCCS-procedure is called train identification; the train should remain in this phase.
Depending on the train's length, the identification takes about 2 to 10 seconds. During the identifi-
cation, the locomotive can of course be controlled and driven as usual. The identification may only
take slightly more time during certain driving situations.
