He started his working life as an air-to-ground missile designer for Hunting Engineering from 1982, before moving into IT services with the American consultancy group EDS in 1985 which led to working on the Oyster card. In 1999 he formed a transport consultancy, Coucher Pender Ltd, in partnership with a colleague Victoria Pender. Through the consultancy, they provided freelance management services to Tube Lines, one of the infrastructure maintenance companies under the London Undergroundpublic-private partnership in which the company was responsible for modernizing three tube lines, with Coucher serving as Tube Lines' Chief Executive from 1999–2001.
Network Rail
Coucher Pender Ltd also provided consultancy for the creation of the railway infrastructure company Network Rail following the collapse of Railtrack in 2002. Coucher was made Deputy Chief Executive of Network Rail in 2002, stepping up to the role of Chief Executive in July 2007 following the retirement of Chief Executive John Armitt. Network Rail paid Coucher an annual salary of £613,000. Coucher announced on 17 June 2010 that he would step down as Chief Executive of Network Rail stating that this was for personal reasons. He remained in situ while his successor was sought. Coucher officially left Network Rail on 29 October 2010, accepting a payment from the company of £1.6 million. Coucher's successor, David Higgins, started on 1 February 2011. Coucher was the subject of controversy regarding his management techniques following allegations in the media by the Transport Salaried Staffs' Association about bullying of Network Rail staff and financial impropriety involving Victoria Pender. An internal examination in 2010 by Network Rail cleared Coucher of any wrongdoing. An independent enquiry headed by Anthony White QC in 2011 further examined the claims, but also exonerated Coucher.
