Class 460 (or 8Gat) was the designation of a fleet of 8-car electric multiple-unit trains built by Alstom at Washwood Heath in 1999-2001. They were part of Alstom's "Juniper" family, which also includes the 334 and 458 classes.

From their introduction until the final units were withdrawn in September 2012, they operated Gatwick Express services between London Victoria and Gatwick Airport. All have since been converted to class 458/5 units (other than four surplus driving vehicles used as spares donors) for operation by South West Trains.

When National Express won the Gatwick Express franchise, part of the agreement was to replace the ageing Class 73/2 locomotives, British Rail Class 488 coaching stock, and Class 489 motor luggage vans. Therefore, an order was placed with Alstom for the construction of eight Class 460 units.[2]

Deliveries of the new units began in 2000. The units featured sloping cab-ends, which earned them the nickname Darth Vaders among rail enthusiasts. A Juniper coupler is located under the removable nose cone although only intended for emergency use.

Each 8-car unit was formed of a driving motor luggage van, two intermediate 1st-class/composite trailers, two intermediate 2nd-class motor carriages, an intermediate 2nd-class trailer, another 2nd-class motor carriage, and a 2nd-class driving motor (DMLFO+TFO+TCO+MSO+MSO+TSO+MSO+DMSO).[2][3]

They were mechanically similar to the Class 458s operated by South West Trains, but the "Darth Vader" nose cones on the Class 460s look very different from the Class 458s' flat cab fronts. The windows in the doors on the Class 460 were also smaller than on the Class 458.

On 22 June 2008 the fleet was transferred to Southern when the Gatwick Express franchise was incorporated into the Southern franchise.[4]

From December 2010 the Class 460s were gradually withdrawn from service in favour of refurbished Class 442s, with the final units going off lease in September 2012. The Class 460s were allocated to Stewarts Lane Depot.

Converted to Class 458/5

On 23 December 2011 the Department for Transport announced that the Class 460s would be split up and sixty carriages rebuilt to be incorporated with South West Trains' one hundred and twenty Class 458 carriages (30 4-car units), resulting in 36 five-car Class 458/5 sets. The remaining four carriages were stripped for spares and then scrapped. This £42m scheme was devised by Porterbrook the owner of both fleets.[5] The new 5-car sets were designated Class 458/5 and coupled together to form 10-car trains to provide extra peak capacity on suburban services into London Waterloo.[6][7]

Porterbrook signed the deal with South West Trains in January 2012.[8] The work was carried out by Wabtec's Doncaster Works and Brush Traction, Loughborough (Drive vehicles) on behalf of original builder Alstom.

The first two of the 5-car sets were delivered in October 2013, and underwent testing ahead of the introduction of the first 10-car train into service in December 2013. Passenger service started in March 2014.[9][10]

It involved replacing the existing retractable gangways and couplers between coaches. The cab ends both on Class 458 and on Class 460 driving vehicles were redesigned to be compatible with the Class 450 Desiro fleet. The "Darth Vader" nose cones were discarded. New Train Management System software was installed to improve reliability. Internal refurbishment included reconfiguring the seating layout to provide more standing room for passengers.[5]

Traction units on the Class 460 vehicles were to be re-geared from 100 mph (161 km/h) maximum, not required on the services for which the trains will be used, to 75 mph (121 km/h) maximum to avoid overheating. Automatic Selective Door Opening was installed for use at a few suburban stations where it is not practicable to lengthen platforms.[5]
