Installing a DCC decoder in a Hornby T9 Steam Loco

Click on each image for a more detailed view.


This installation really is one of the easiest in a steam loco as the engine is DCC ready.

Before installing chip into any loco it is advisable to check the current being drawn by the loco. To remove the body there is one screw in the smoke stack.

T9 tender Screw in tender

The loco is DCC ready, having a socket installed in the tender of the loco. It is necessary to lever out the coupling from its mounting.

Once the coupling has been removed a screw is revealed which holds the tender body to the chassis. Remove this screw and gently remove the tender body.


Location of socket in T9 tender

Gently lever the dummy plug out of the socket. This reveals the socket, with pin 1 clearly labelled.

T9 with TCS DP2X-UK decoder installed

This installation used a TCS DP2X-UK decoder, a plug-and-play decoder with no wires. Check the orientation of the decoder to ensure Pin 1 is correctly identified and firmly push the decoder into the socket, being careful not to bend the pins.

If you wish to remove the capacitor this can be done by carefully cutting out the device by snipping the legs of the capacitor, as close to the device as possible.

It is suggested that you do any programming of the decoder at this point, before replacing the body.

Replace the body, fit the screw and replace the coupling.
