During Summer 1961, LMR chose and wrote to 18 regiments about their desire to have these names placed on new Peak Locomotives, probably D50 - D67, given that these were now to be the last delivered after the constuction of them was moved from Derby Works to Crewe Works for introduction to traffic in early 1962. The regiments were keen to have their name on a loco, and have the nameplate from the steam engine of the same name as a momento. The locos and regiments were as follows:
- 45502 Royal Naval Division
- 45503 Royal Leicestershire Regiment
- 45504 Royal Signals
- 45507 Royal Tank Corps
- 45509 Derbyshire Yeomanry
- 46112 Sherwood Forester
- 46118 Royal Welsh Fusilier
- 46119 Lancashire Fusilier
- 46122 Royal Ulster Rifleman
- 46123 Royal Irish Fusilier
- 46132 King's Regiment Liverpool
- 46134 Cheshire Regiment
- 46138 London Irish Rifleman
- 46141 North Staffordshire Regiment
- 46143 South Staffordshire Regiment
- 46148 Manchester Regiment
- 46149 Middlesex Regiment
- 46158 Loyal Regiment
Despite the desire of the regiments, however, only six of these were eventually chosen, plus three others whose names were changed slightly. The plan to put the names on new loco's was soon dismissed when, on 23rd September 1961, D100 was named Sherwood Forester, and ultimately only D163, in April 1962, would enter traffic as a named locomotive. A further 25 locos were eventually named, a very protracted process that took until January 1967. Of these, fifteen of D50 - D67 were named, but it appears naming happened, for the most part, when locos received repaints at overhaul. A further two loco's, D74(45 051) and D86(45 105) (carried bolts from 1967 onwards) appear to have been in line to be named in 1967, but the plug was pulled before this could happen, naming of locos smacked of elitism that didn't sit well with BR's new corporate identity!
The locos named follow in order of their naming.
