The Stroudley Brighton Terriers were one of the most successful designs of tank locomotive to run on the railways of Britain. They were introduced in 1872 and operated in main line service until November 1963, when ten members of the class were preserved both officially and by heritage railways. This volume tells the facinating story of there service and operational life, both on the main line and later when many of them had a further existence on light railways and in industry. John Scott-Morgan and Peter Steer have spent many hours reserching the interesting history of these Victorian survivors that operated long after there original lifespan on many railways across Britain.
