Scheidt & Bachmann had initially gained experience in the design and manufacture of self-service ticket machines during the 1990s when the FAA-2000 system, popular on continental European railway networks, was developed. By the early 2000s a refined design, marketed as FAA-2000/TS, had been launched. Its modern touch-screen technology, flexible and easily customisable interface and ability to accept cash or card payments made it a popular choice with transport operators in urban areas including Boston, New York City, Seattle, Cologne, Copenhagen and Dublin. A version of this newer design with the codename FAA-2000/TS (ATOC) was put on trial in August 2003 at Twickenham, a South West Trains station. In conjunction with the redesign and rebuilding of the station forecourt area, two Ticket XPress machines—numbered 2000 and 2001—were built into a wall next to the main station entrance.
