Class 107 (11 vehicles)
Class 107s are similar in appearance to the standard Derby Class 108. One of the major differences between them is that the Class 107s have steel bodysides and not aluminium. They were also almost exclusively used in Scotland. All the units were originally built as 3-car sets.
Considering how less attractive the steel (rather than alloy) bodies would prove to be, a good number of Class 107s have been preserved, five sets, with none having yet been scrapped after preservation. Only a single authentic 3-car formation survives, the rest being preserved as 2-car sets.
2022 & 2023 were major years for the class, with ten out of the eleven vehicles being sold and moved to new homes. This significantly shifted the landscape for the class but fortunately two sets remained based in their native Scotland.
Unfortunately the class has spent large numbers of years with almost the entire fleet inactive in one way or another, with very few vehicles settling down into regular service or kept in good condition. As a result, they have become somewhat rare to experience in traffic.
By the mid 2020's, two out of the five sets could be seen in operational service, with a third under restoration, so things have steadily started to improve, and will hopefully continue to do so.
