90001-90050 / Class 90

Numbered 90001 to 90050 as built.

Several Class 90s had their buckeye couplings removed and ETS supplies isolated for a period and were renumbered into the 90/1 series to reflect these changes carrying over their numerical identities by retaining the last two digits in that 90026 became 90126. All were subsequently returned to standard and renumbered back into the 90/0 series regaining their original numbers.

Another numbering venture involved several Class 90s that had their brake force characteristics modified and these were renumbered into the 90/2 series, again retaining their numerical identities by retaining their last two digits. Some of the Class 90s that had earlier been renumbered into the 901XX number range also featured in the 902XX series once modified. All were later returned to standard Class 90s regaining their respective 900XX numbers.
