The National Railway Museum's most significant event since the opening in 1975, has to be its celebration of 200 years of steam railways, which took place under the title Railfest 2004. It celebrated two remarkable railway anniversaries, the operation of Trevithick's Penydarren engine at Merthyr Tydfil, South Wales in 1804, and the Great Western Railway's 100mph run withCity of Truroin 1904. So, any celebration held at the world's largest railway museum had to feature both the replica Trevithick engine and alsoCity of Truro. Planning for an event which became Railfest started years earlier and drew inspiration from Railfair 99 in California, London 2000 and the earlier national rail celebrations at Shildon in 1975 and Rainhill in 1980. Using just a small team of staff and many volunteers, the NRM created one of the biggest railway events ever held, and one that will be remembered for a very long time to come.
