Tri-mode multiple-unit passenger train From Wikipedia, the free encyclopedia
The British Rail Class 756 FLIRT[7] is a class of tri-mode multiple units built for Transport for Wales Rail by Swiss rolling stock manufacturer Stadler Rail. They are closely related to the Class 755 bi-mode units delivered by Stadler to Greater Anglia between 2018 and 2020, which can be powered either by overhead electric lines or on-board diesel generators. The Class 756 units also carry batteries as an additional source of traction power.[citation needed]

The Wales & Borders rail franchise, awarded to KeolisAmey Wales with effect from 14 October 2018, included a commitment requiring that the operator oversee a full fleet replacement during the franchise period.[8] As part of this process, KeolisAmey placed an order with Stadler in February 2019 for the 24 FLIRT tri-mode units that came to be designated Class 756. The tri-mode capabilities are intended to facilitate operations over lines that have only been partially electrified. Production of the fleet was underway by mid-2021.[2]
The Class 756 entered service on 15 November 2024[1] and then again from 18 November 2024 onwards.[9][10]
Transport for Wales Rail Class 756 units currently operate services between Cardiff-Merthyr Tydfil and Cardiff-Aberdare.[1]
Class 756 units have three or four passenger vehicles, along with a separate "Power Pack" vehicle near the centre of the unit that contains a diesel generator set and three battery modules.[11] The diesel generator produces 480 kW (640 hp), while the batteries are capable of supplying up to 1,300 kW (1,700 hp).[6] All vehicles are linked by unpowered Jacobs bogies, while the outermost bogie at each end of each unit carries the traction motors.[6]
