- 1952, Cuthbert Hamilton Ellis, The Beauty of Old Trains, page 117:
- The 2-4-2 tank engines of the Great Eastern and the London and North Western were simply adaptations of 2-4-0 main-line engines; the 0-4-4 tank engine owed its parentage to the archaic 0-4-2 mixed traffic.
- 1988, Edgar J. Larkin, The Railway Workshops of Britain, 1823-1986, page 52:
- After five 0-4-2 saddle tanks in 1860, all other NLR motive power was constructed at Bow, and none of these early locomotives was fitted with a cab.
- 1975, M. A. Rao, Indian Railways, page 143:
- The 'Lord Falkland', which pulled the first train from Bombay to Thana on April 14, 1853 was built by the Vulcan Foundry in England and was a '2-4-0' tender engine. This was followed by other locomotives of the 2-4-0, 2-2-0 and 0-4-2 types, which continued in use for a number of years.
