TCS DP2X-UK Decoder Installation for HO-Scale Hornby Great Western Railway King class locomotive. It was performed by Robert Lewis of Tilehust, Reading, United Kingdom
Here is a Hornby model of a Great Western Railway King class locomotive. The King class were the pinnacle of Great Western engineering, pulling the fast expresses from London to the West of England and Wales, they were more powerful than some of the larger locomotives built by the other 3 British regions.
To remove the body it is necessary to undo the slotted screw located under the front pony truck, if you use a thin shafted screwdriver it is possible to skew the truck to one side to gain access, otherwise you will have to remove the 3 cross headed screws between the main driving wheels to remove the whole bottom plate ( not recommended) and disturb the pick ups and driving wheel axles. Once the screw is removed, lift the body from the front, it is hooked over a metal tab just under the drivers cab, once the front is clear of the motor the body can be slid back a few millimetres to detach it from the rear of the chassis.
Here is a picture of the decoder socket with the blanking plate removed.
And here is the TCS DP2X-UK installed.
The installation should be tested on the test track to ensure the decoder has been fitted correctly, and then the body refitted, rear end first.
