After ScotRail, the next large-scale adopters of Ticket XPress machines were South Eastern Trains. They submitted a request for tender in February 2004, and six months later the first four machines were installed on their network: two each at Beckenham Junction and Eltham. The programme was expected to be complete in March 2005; this timescale was not met, but by August 2005 South Eastern Trains had installed 141 machines. More orders came from other TOCs throughout 2005 and 2006. Central Trains began in February 2005 by putting in machines at seven Cross-City Line stations and at Walsall. National Express East Anglia ordered 75 Ticket XPress machines in April 2006 and installed them at 38 stations as direct replacements for Ascom B8050 Quickfare machines. The order was worth more than £2 million based on the installation cost of each machine. The company had been trialling four machines at London Liverpool Street station since July 2004 and one at Chadwell Heath since April 2005. Merseyrail acquired its first machine in August 2005 and installed it at Liverpool Central; at the same time the Wales & Borders TOC put a machine on trial at Chester. In late 2005, Wessex Trains and Silverlink ordered Ticket XPress machines. For the former, Cheltenham Spa, Gloucester and Truro were among the early installations; neither these nor any other Wessex Trains station had self-service ticket machines previously. At stations on the Silverlink network, a mixture of old Ascom B8050 Quickfare and Avantix B8070 machines were replaced by the new technology; stations on the West Coast Main Line between Berkhamsted and Wolverton were equipped first, followed by North London Line stations by January 2006. In early 2006, Virgin Trains put a single trial machine in place at a rarely used side entrance to Preston.
