Steam locomotive and tender, Grand Junction Railway, (London & North Western Railway), 2-2-2 No 49, "Columbine", designed by Alexander Allen, built at Crewe Works in 1845, withdrawn in 1902, cab separated from locomotive.

This locomotive was the first example of the standard ‘Crewe’-type engine with 6ft diameter driving wheels. Many of the early locomotives had inside cylinders, driving on to a crank axle which was a source of weakness. W B Buddicom and Francis Trevithick (son of Richard) accordingly developed the outside cylinder design which influenced British locomotive thinking for more than forty years. The locomotive has had its cab removed so that it appears as it did in the early 1870s.
