Great! When you get time would love to see them. My best mate and I were 14 in 1984/5 and got involved just after closure of the Yard with the NDSR and spent many an hour there cleaning Ajax, cleaning the two Tube carriages, riding around in wagons and generally revelling amongst the filth and industrial decay of that place....
We even had jobs on the underground stock on the couple of odd open days that where held, operating the doors, etc. I have some odd pics, one of the Fowler DM 0-4-0 (my favourite, now sadly gone loco there), the underground train with Ajax at the head, and a postcard produced by the society after the first open day and that's it! Would love to see more....
