Ok, very nearly there!
All glazing, buffers and detail parts have been attached, sound chip has been installed and is working fine but needs to have a suitable file loaded to it. I also attached steps to the bogies, these were made from repurposed HO caboose ladders. Here's some pics of 019 sitting on the tracks....
I had a bit of an issue with the lighting. Specifically, the Hornby PCB that I used is wired with a negative common as opposed to a positive. My homemade led boards were wired positive so they had to be scrapped. I installed the boards and soldered in the connections. To prevent light bleed I gave the boards and leds several coats of primer then drilled small holes in the top of each led, fibre optic strands will be fitted into the marker/tailights when all else is done!
Here's a couple of pics of the chassis with the lights activated:
