An application by SWT to extend this by six months was refused, as the class did not meet all the requirements of disability legislation. However, later it was decided that, on or before the start of the new franchise in February 2007, the class would be reinstated and take over all operations on the Waterloo to Reading line, indirectly covering the loss of the Class 442. They have been fitted with new, larger destination screens that comply with the disability legislation, but the trains still fall foul in some other areas, such as the height of the door-open buttons. All 30 Class 458 trains were split up and the 120 vehicles reconfigured into 36 five-car sets, incorporating 60 extra vehicles from the mechanically similar formerly used on Gatwick Express services. The five-car sets are now designated Class 458/5 and coupled together to form ten-car trains from 2014. The first two of the five-car sets were delivered in October 2013, and underwent testing ahead of the introduction of the first ten-car train into service in December 2013. Passenger service started in March 2014, with the work concluding in 2016, thereby rendering the Class 458/0 extinct. South West Trains had 11 two-car units and 30 three-car units (22 Class 159/0 and eight Class 159/1). The Class 159/1 units were converted at Wabtec, Doncaster from Class 158s, received from First TransPennine Express in exchange for s. Eleven further two-car Class 158 units were received from First TransPennine Express, which were also refurbished at Wabtec. Two Class 158 units transferred from Central Trains entered service in July 2005 on the new Bristol Temple Meads service, moving to First ScotRail in February 2007. The Class 159 has on occasion been used for railtours. Although South West Trains did not operate locomotive-hauled services, until 2009 it maintained three locomotives for recovery duties. Locomotive 73109 had been in service with SWT since the start of the franchise; the other two, 73201 and 73235, were acquired from Gatwick Express in 2005. 73235 was the only one of the three locomotives to be owned by South West Trains at the end of the Franchise. Former units operated by South West Trains include: These units were initially dedicated to the Weymouth line but, in the 1990s, began to be operated on the London to Portsmouth direct line also. In preparation for the Class 444 and Class 450 "Desiro" units taking over from the slam-door fleet, the Wessex Electrics were withdrawn from Portsmouth line services and were again wholly dedicated to the Weymouth line.
