ROLLING STOCK
Chris Fawdry and Jamie Foster with Kate Green and members of the Lucchini team in front of IEP power and trailer wheelsets.
trailer wheelsets the axle has been designed using the new British Standard BS5892 Part 8.
The general design of the wheels is similar for each type of wheelset and manufactured from ER8 grade steel with a P8 profi le. TSI approval on the wheel has already been obtained.
The trains will be delivered as fi ve-car and nine- car units with the following confi guration: • Five-car: 12 power wheelsets and eight outboard bearing trailer wheelsets; • Nine-car: 20 power wheelsets, eight outboard bearing wheelsets and eight inboard bearing trailer wheelsets.
The steel for the wheels and axles is manufactured in Lucchini RS group’s electric arc furnace in Lovere; the wheels are forged, rolled and heat-treated in the completely new wheel production facility before being shipped to LUK for fi nish machining. The axles are forged in Lovere, but are also fi nish machined there, since axles destined for power wheelsets must fi rst be delivered to the gearbox manufacturer in Germany before LUK
receives them in Manchester for assembly of the wheelsets.
All the wheelsets will be assembled at LUK, using brake discs from Knorr- Bremse and axle bearings from NSK. A rigorous series of non-destructive tests is carried out on the wheelsets – a ‘belt and braces’ approach, since the wheels and axles also undergo non-destructive testing as loose components.
The IEP project will, in total, call for some 3,500 wheelsets. To date LUK has received call-off orders for phase 1 of East Coast Mainline and the Great Western Mainline tranche, representing around 2,400 wheelsets.
We have already delivered the fi rst wheelsets to Hitachi’s Kasado plant in Japan for assembly onto bogies as part of three prototype trains that will go on test for a year before the series build starts in Hitachi’s new plant in Newton Aycliffe in 2016. Phase 2 of the ECML project
workforce in Manchester busy for a few years yet – and ensure that these superb new trains will be equipped with wheelsets made in Britain to the highest of standards.
