Lists of locomotives on Works are valuable evidence for determining when modifications to locomotives took place, for example steam heat generator removals (see Diesel Dilemmas and thread on this forum), and repairs after collisions and fires (see Query Corner). For some time now I have been compiling a spreadsheet listing Doncaster Works reports and the class 31 locomotives recorded as being on works. I have been through back issues of RO and various other publications. This is an appeal for help to fill in gaps. I'd be grateful if anyone is able to provide Doncaster Works lists for any dates not in RO, particularly the following: March 66 to July 74 any! 1975 Mar/Apr/Jun/Jul/Sep/Dec 1976 Jan/Mar/Sep 1977 Jun/Jul/Sep/Dec 1978 Jul/Aug/Nov 1979 Jan/Feb/Apr/May/Aug/Sep Thanks!
Regretably no pre 1975 photos and rarely recorded livery variants in those days despite seeing many in green in the Crimpsall shops during overhaul (and out and about at that time. It wasnt unusual enough to record it then).
5818 (arrived Doncaster 20/03/74) and 31294 (arrived Doncaster 06/03/74) were actually the last green class 31s. 31294 is reckoned to be the only class 31 to carry a TOPS number in green livery, but I'm on the look out for good evidence to substantiate that. Your report confirms that 5818 arrived on works unrenumbered. 31294 departed on 07/04/74 in blue and it would have been nice if it could be confirmed that it hadn't already been in the paint shop before 30/03/74.
It is also interesting that you recorded 5697 as such. This became 31419, and I have never been able to pin down an exact date that it departed the works, so your report at least narrows the range down a bit.
Finally, you mention that you saw many green class 31s in the Crimpsall: does that mean that you have some lists from dates earlier than 30/03/74?
