The '''British Rail Class 124''' [[diesel multiple unit]]s were built by BR [[Swindon Works]] in 1960.

==Operational history==
{{unreferenced section|date=July 2017}}
The Class 124 was a class of initially six-car [[diesel multiple unit]]s used and built specifically for the [[Huddersfield Line|trans-Pennine route]]. In the late 1970s, the class was merged with their [[British Rail Class 123|Class 123]] cousins that had been relocated from Reading services on the [[Western Region of British Railways|Western Region]] and, towards the end of their days, ran as 4-car hybrid sets. They were all withdrawn in 1984 when their duties were taken over by [[British Rail Class 31#Class 31.2F4|Class 31/4]] diesel-electric locomotive-hauled rakes of four coaches.

Nine 2-car sets composed of a [[British Rail Class 123|class 123]] DMBSL and class 124 DMC were formed at Hull in 1984 in case introduction of the [[British Rail Class 141|class 141 'Pacer']] units was delayed, but they were never used in service.

The [[North Yorkshire Moors Railway]] had the idea of preserving at least one driving unit, due to the cab windows allowing panoramic views, but the plan was scrapped when it was found that the cost of removing the asbestos from the vehicle was prohibitive.

The class was not unique; the Class 124 DMUs shared mechanical components with their sister class 123, on the Western Region, and the [[British Rail Class 126|Class 126]].

'Wrap-around' windscreens were a feature that was also seen on the 'Glasgow Blue Train' [[British Rail Class 303|Class 303]] and [[British Rail Class 311|311]] electric units; they were also seen on the [[Great Eastern Main Line|GEML]]'s [[British Rail Class 309|Class 309]]s and the [[West Coast Main Line|WCML]]'s [[British Rail Class 310|Class 310]]s, although these were later modified to cut replacement costs.

==Numbering==

! Lot No. !! Type !! Diagram !! Qty !! Fleet numbers !! Notes

| 30603 || Driving Motor Open Composite (DMC) || 577 || 17 || 51951–51967 || 21 first, 36 second seats;

|-
|}

In later years when operating as 4-car units, the MBSL had their engines removed to reduce maintenance, as it was deemed two Motor Vehicles were adequate. To show this change the remaining MBSL were renumbered on removal of the engines.

==Liveries==

They were initially introduced in a green livery, but they never carried the common 'Whiskers' that many DMUs of the time carried. A small yellow panel was added at a later date to the cab front.

They ended their days in then standard BR blue/grey livery.
