Changes

:I've added a comment on the renaming. The entries are already linked to the 20007 50007 Loco page, which in turn mentions the gala appearances and the renaming.--[[User:Robin|Robin]] ([[User talk:Robin|talk]]) 17:52, 12 December 2016 (UTC) Prompted by Patrick's comment on Nat Pres that the first ever SVR Diesel Gala was held in May 1987, this page began with 1986 as the Stock Book 9th edition stated that the first visiting diesel was in March of that year. However SVR News suggests it was at Kidderminster as a static exhibit which explains the discrepancy.
