For the InterCity 125, see British Rail class 43. The Class 125 was a design of three car Diesel Multiple Unit built by British Rail in 1958. They were high-density units, externally very similar to the Class 116. They were built specifically for the Lea Valley Line based at Stratford, but were displaced to the ECML suburban lines out of Kings Cross when the Lea Valley Line received 25 kV overhead electrification in May 1969. The class were all withdrawn in 1977 when the ECML suburban lines received 25 kV overhead electrification, and none survive to this day. Like many first-generation DMU classes, they never carried their 125xxx TOPS set numbers. Numbering
LiveriesThey were delivered in an unlined medium shade of Brunswick green with white cab roofs and yellow speed whiskers. The whiskers were replaced during the early 1960s by split yellow warning panels, one either side of the central character train describer which remained green. During the mid 1960s rail blue appeared, and white cab roofs were gradually dispensed with and buffer beams became black. Initially the yellow warning panels were expanded to cover the complete lower front of the driving cabs and later the whole cab fronts became yellow. References
