| South West Trains' class 444 is the mainline 3rd rail
dc member of the Siemens Desiro EMU family. There will be 45 units in this
class. As slam door stock replacements they inherit the services formerly
worked by C/Beps and Cigs. Each unit is formed with five 23m airconditioned
cars DMCO-TSO-TSO-TSRMB-DMSO gangwayed throughout and befitting its mainline
role has single plug doors towards the end of each car. Seating is in open
saloons 2+1 facing and unidirectional in first class (35 passengers) and 2+2
facing and unidirectional in standard (299 passengers). These units carry
SWT's mainline white and blue livery as worn by classes 159, 170, 442 and, inappropriately, class 458. There is space for two wheelchairs and also
three bicycles in two separate "multi-purpose" areas. Each unit has
four toilets, one being wheelchair accessible, and a mini buffet serving
beverages and cold food. For security, closed circuit television cameras are
fitted in each passenger saloon and are monitored in the Train Manager's
office. An audio visual Passenger Information System (PIS) is installed.
Full information about the procurement and maintenance of these trains can be found in our Class 450 Desiro pages. Self-supporting aluminium extrusions are utilised in the welded construction. Each five car unit has four 1TB2016-0GB02 asynchronous traction motors. The starting tractive effort is 200kN and the continuous rating is 150kW. The bogies are of the steel mainframe SGP SF5000 type with the primary suspension being of coiled springs, secondary being supplied by air bags. Dellner couplers are fitted at unit ends. Traction equipment is mounted in resilient boxes between bogies to reduce the amount of vibration in the passenger saloons. Disc and rheostatic brake systems are fitted and top speed is 100 mph. They can work in multiple with class 450 units These trains were built at Siemens' plant in Vienna, the first, 444001, being unveiled on 12th November 2002. They are tested at the Wildenwrath facility (see our class 450 pages for further details). Delivery to the UK is via the Channel Tunnel. The first unit to be delivered was 444011 which arrived at Eastleigh on 6th November 2003 and was delivered to Northam two days later. To gain type approval slow speed testing was undertaken between Bournemouth and Weymouth for which a possession was required. This testing was completed during February 2004. As a result Siemens made a submission for a certificate to run at a maximum of 85mph. In turn this allowed mileage accumulation with two ten-car trains running empty towards the end of March. Services, limited to 85mph (with a 40 mph restriction through Buriton tunnel), started on the Portsmouth direct line on 21st April. Units N°444018 and N°444019 worked the 8:18am Havant-Waterloo service follwed by 10:08am, 2:08pm and 6:15pm Waterloo-Portsmouth Harbour diagrams. This policy of restricting to 85mph running permitted the units to be introduced more quickly than waiting for full 100mph approval. High speed testing started between Woking and Winchfield over the weekend of 21st/22nd February 2004. Once testing was complete and the 100mph certificate was received SWT was able to start introducing Class 444s onto Waterloo - Portsmouth via Eastleigh services with plans to run Class 444s Waterloo - Portsmouth via Guildford, Waterloo - Portsmouth via Eastleigh, Waterloo - Haslemere, Waterloo - Southampton, Wareham - Brockenhurst and Brighton - Basingstoke (diagrams not covered by Class 170s). Depending upon diagram considerations it was believed Class 444s might run Portsmouth-Southampton services. Class 442s will remain the prime stock on Waterloo-Bournemouth, Waterloo-Poole and Waterloo-Weymouth services.< |
