This may help as these were present the day before:
Nearest mainline (north to south): 56007(blue), 56038(Fertis), 56077(Loadhaul), 56103(DCRail)
Elsewhere: 37905 (green), 37906 (grey/yellow), 37003(blue), 27059(primer), 47813(blue), 47843(blue, at the back, no bogies), 47847(blue), 56060(Fertis), 56065(Fertis), 56091(grey) 56106(grey, one cab missing), 58016(grey)
Non of the above (with the exception of 56103) moves except around the site as they are all stored or under repair. 47812 arrived from Castle Donington today at 12:40.
If there was a blue Class 50 it was 50008, and if they were present the two burgundy / cream 57s were 57305 and 57312. I can't help on any Europhoenix / ROG 37s that might have been around.
I hope this gives you enough to piece together what you've seen.
