Northern Rail has introduced new trains at Southport as it continues to replace its ageing Pacer trains.
Eight new Class 769 bi-mode FLEX trains have been added and began by running on the Southport-Stalybridge/Alderley Edge route which passes through West Lancashire and Manchester.
The trains, constructed by Porterbrook in partnership with Wabtec/Brush, are designed to run using overhead lines or diesel engines and can switch between the two while running, allowing them to be used on electrified and non-electrified routes.
They are also larger than the previously used trains, adding more capacity on journeys.
Chris Jackson, Regional Director at Northern, said: “We are really proud to be involved in this pioneering development. Bi-mode trains bring the benefits of railway modernisation, to more customers, more quickly.
“Northern is determined to make a positive impact for the north of England and this technology opens up new opportunities to spread the benefits of electrification to non-electrified routes, delivering more efficient journeys and increased capacity for our customers.”
FLEX trains operate by having diesel powered alternators under each of the driving trailer cars. The diesel alternators provide power to the existing traction and auxiliary equipment to allow the former EMU to operate without an overhead or 3rd rail supply.
The systems provide power through the trains’ DC bus, avoiding any significant changes to the existing equipment and creating a unit capable of operating from different power sources whilst maintaining its full capabilities on electrified routes.
Mary Grant, CEO of Porterbrook, said: “The introduction of the FLEX fleet into traffic is the result of a collaborative partnership between Northern, Porterbrook and our suppliers. I would like to thank Northern for their unstinting commitment to the successful introduction of this highly innovative fleet, as well as my own team for their relentless focus on the needs of our customer.
“The bi-mode capability of the Class 769 fleet will ensure that communities across the Southport – Alderley Edge route can share in the benefits of electrification.”
