Cawnpore–Burhwal Railway was sanctioned for construction in October 1894 to provide a link between the metre gauge railways, north of the Ganga river with the Rajputana-Malwa Railway system. The construction was commenced in November 1894. The line was constructed alongside the broad gauge from Cawnpore via Lucknow to a junction with Bengal and North Western Railway at Burhwal 160 km away. The metre gauge line between Burhwal and Daliganj on the Lucknow–Bareilly Railway was opened on 24 November 1896. The line was later extended to Barabanki. The line was 29 km long.
