Upon his retirement in 1987 he was replaced by Robert Smith, whose style was totally different and who made many changes. Smith masterminded the Year of Railways in 1993 and the celebrations that followed. Rolling stock returned to original "purple lake" livery and No.s 10, 15 and 1 (in that order) were returned to service. When he resigned in 1999 he was replaced by David Howard, with previous bus experience at various UK operators and rail experience from his time at Tyne and Wear Metro. He was more inclined to a corporate approach and the railway had to follow suit. His time in office, finishing in 2006, will be remembered for the thrust on health and safety issues, such as high-visibility clothing and warning signs, as part of a Government-wide drive. The government commissioned a study to see if it would be worthwhile to operate commuter services to help relieve the road traffic congestion in and around Douglas, and although experimental services were implemented in 2007, these operate only during T.T. race periods. The study recommended against such development. Nevertheless, almost all the line was relaid in the first few years of this century as part of the Department of Transport's IRIS sewerage scheme, with all but one of the numerous level crossings converted from manual to automatic operation, saving the cost of employing crossing keepers. After Howard resigned, the Department of Tourism and Leisure's Director of Leisure, Mike Ball, stepped in as acting director of public transport, and in early 2007 the leisure and public transport divisions of the department combined into "service delivery", Ball becoming "Director of service delivery" under the minister Adrian Earnshaw appointed in November 2006. Ian Longworth was appointed Director of Public Transport in 2009 and since then the railway has become part of the Department of Community, Culture and Leisure. A number of new services have been introduced since the arrival of the new director, including evening excursion trains, a Rush Hour event at the start of each season, and family-oriented events including a "Teddy Bears' Picnic" and "Fathers' Day" specials. A restoration programme for the unique collection of rolling stock and locomotives is ongoing; this has seen most recently two saloon-type coaches completely rebuilt and back in traffic; at least three more coaches are to be restored, one of which has been out of traffic for nearly half a century.
