Well, here's a few points from this Wikipedia article which may be of interest.
http://en.wikipedia.org/wiki/List_of_locomotives_saved_from_Woodham_Brothers_scrapyard
a. 43924 (MR 3835) Class 4F was the first locomotive to leave in September
1968. It's now on the Keighley and Worth Valley Railway and is operational.
b. 5553 GWR 4575 Class was the last locomotive to leave in January 1990. It's now at Crewe Heritage Centre.
c. 2807 GWR 2800 Class was the oldest locomotive to be saved, in June
1981. It's now operational at the Gloucestershire Warwickshire Railway.
d. 3612 GWR 5700 Class was saved in December 1978, but has been dismantled for spare parts.
e. 42859 LMS Hughes Crab 6P5F Class was saved in December 1986 to a private site. However, they claim that the boiler has been scrapped, with the frames and wheels stored at separate sites.
f. 4253 GWR 4200 Class, saved in August 1987 is under restoration on the Kent and East Sussex Railway.
g. 4156 and 92085 are unsurprisingly not on the list. The list does show that 30841 SR Maunsell S15 Class was saved in September 1972 and moved to the North Yorkshire Moors Railway Despite being named Greene King in preservation it has since been dismantled, with the boiler and tender on fellow Maunsell S15 825, another survivor from Barry.
and finally ....
h. 92219 BR Standard Class 9F was saved in May 1985 and is at the Wensleydale Railway in unrestored condition. It is the penultimate steam locomotive built for British Railways, but the newest one saved from Barry.
I hope that this helps!
