Here's a photo sequence of installing the TCS DP2X-UK decoder in a Bachmann class 08 shunter
First undo the screw buried under the rear coupling mount.
Then release the offset clip shown in this photo:
Now you can hinge the body back and release the front lug which clips under the front footplate
The decoder socket is at the front. I was a bit worried when I saw that the socket was offset
Here's a photo of the remarkably small but perfectly formed TCS DP2X-UK. The object on the right is the Bachmann coupling. I put it there as a size reference.
The decoder socket has a 1 marked on the circuit board and the TCS documentation has a diagram from which you can work out where pin one is. My interpretation ended up looking like the photo below. It looks like I need not have worried about the offset socket location.
A quick check on the programming track that the loco works followed by a change of address. Now the moment of truth; will the body go back on?
No problems with clearance for the body.
So long as you know how to get the body off, this has got to be one of the quickest conversions there is. The elapsed time between the first photo and the last was 9 minutes. It took longer to resize and upload the photos and then add them to this text
