LCDR Echo class

The Echo class was a group of five steam locomotives designed by Thomas Russell Crampton for the London, Chatham and Dover Railway, which wanted fast first class passenger engines for its new lines. They were ordered from Robert Stephenson and Company in 1860 at 3,400 pounds each and delivered between March and May 1862, built as 4-2-0 engines with the Cudworth coal-burning firebox also used on the railway's Tiger and Acis classes. They were rebuilt as 4-4-0 locomotives in 1863 and 1864, after only a short time in service. Unnamed at first, they were numbered 27 to 31 in 1875 under the class letter K, four passed to the South Eastern and Chatham Railway in 1899 and the last was withdrawn in August 1906.
