Hi Peter,
Here are a couple of grids I noticed off that site, not the best images, but I'm sure there is more.

56069 with empty HAA's on 11th November 1982
56059 & 56069 stabled at 6G on 24th April 1984 with 47198. The 2 Grids went up the Conwy Valley line to conduct deflection tests on the bridge north of Betws-y-Coed.
One that I really do like, a row of Duffs on 30th August 1986, 47's 100, 331, 349 and 353, and the full yellow ended Rat, 25912 Tamworth Castle.
And a sad one to finish, 40001's last ever revenue earning run, on 5th July 1984 at Mochdre
Hope you don't mind the hijack?
Regards
Jinty ;-)
