Christopher Valkoinen has worked at the National Railway Museum's Search Engine library and archives since 2010 where he is responsible for the digitisation of the archives. His passion is engineering drawings and his mission is to see them recognised for the artistic skill of the draughtsmen that created them, and for the fascinating stories they can illuminate about our history. Christopher is also a qualified steam locomotive fireman and has fired/driven locomotives including Flying Scotsman, City of Truro, Olton Hall (aka Hogwarts Castle) and the working Rocket replica.
