Class 170

The class 170 "Turbostar" is the diesel hydraulic multiple unit designed for longer distance services from builders Adtranz, now Bombardier. Vehicles, which are of nominal 23m long, are of welded aluminium with steel ends construction and all cars are motored providing 422h.p. @ 1900 r.p.m. per car. Units can be formed of either two, three or four cars. Cars are gangwayed within the unit and are air-conditioned. First deliveries of 170/1 two car units began in January 1999 to Midland Mainline.

This class gains eligibility to be included on the SEmG site with the commencement in the May 2000 summer timetable of Anglia Railways' innovative Crosslink Service. Crosslink connects East Anglia to Basingstoke avoiding a change in Central London. There were six services each way Monday to Saturday on a two hourly interval with most currently starting at Chelmsford or Colchester (although a small number start from Ipswich or Norwich). The trains called at Stratford (interchange with First Great Eastern, Docklands Light Railway, Silverlink Metro, and LUL Central and Jubilee Lines), Highbury and Islington (interchange with West Anglia Great Northern, Silverlink Metro and LUL Victoria Line), West Hampstead (interchange with Thameslink, Silverlink Metro and LUL Jubilee Line), Feltham (for Heathrow Airport Gateway), Staines, Woking and Farnborough. From the North London line the service was routed from South Acton junction reaching Southern territory at Old Kew Junction and thence via the Hounslow loop.

For Crosslink Anglia Railways drew on their eight strong fleet of 170/2 three car units which are leased from Porterbrook. Deliveries from Adtranz were between May and July 1999. The units are formed DMCL (driving motor composite lavatory) - MSLRB (motor standard luggage buffet) - DMSL (driving motor standard lavatory).
 
170206 Progress over the North London Line for Crosslink services is slow since they have to fit in between Silverlink Metro stopping services at 15 minute intervals (for most of the day) and many slow moving freight trains. 170206 is passing north/eastbound through South Acton station on 14th June 2000.

The Crosslink service was terminated at the end of the summer 2002 timetable. Although passenger loadings were initially encouraging the service failed to catch on. Additionally train paths along the North London line are tight and the SRA felt that reliability of other services would be improved if line capacity was prioritised on the better used services.

The Southern's association with the class was completely cemented when on 12th December 2000 South West Trains commenced services with its eight two-car 170/3 fleet. Strangely SWT have chosen a first class heavy DMCL - DMCL formation. These units are also leased from Porterbrook. Individual cars are numbered DMCL(A) 50301-8 and DMCL(B) 79301-8. Like SWT's class 159 fleet they are based at Salisbury and 170301 arrived there in October 2000. Further unit arrivals were 170302/3 in early November, 170304/5 on 17th November, 170306 on 23rd November and 170307 on 5th December.

The first service SWT class 170 passenger working was on 12th December 2000 with the 5:10am Salisbury to Southampton using units 170301/2. This formation was then due to work the 5:52am Southampton to Eastleigh service however it was delayed after it was discovered that the safety case for this stock on this route had not been completed - it was by 6:15am when the units eventually departed! 170304 was the first representative of the class to work into Waterloo, doing so on 18th May 2001 with a special from Salisbury. As this was a day of industrial action on South West Trains with 95 percent of services cancelled this happening was missed by many! SWT now regularly work 170s in multiple with their 159s on west of England services into and out of Waterloo.
