Frederick Thomas Granville Walton CIE, M. Inst C.E., Telford Medal, was a notable British railway engineer in India. He specialised in bridge construction. He was commonly known by his middle name Granville, and was often referred to as Mr F.T.G. Walton. Walton was born in September 1840 in Hampton, Middlesex, England to William Walton (1795–1889) of Reading, Berkshire and Elizabeth Louisa Plunkett (1801–1866) originally of Dalston, Cumberland.

Walton studied under Richard Johnson, chief civil engineer of the Great Northern Railways. He then began working at Cheshire Railways as an Assistant Engineer in railway construction in 1860 until 1868. Walton then moved to India and worked for the Oudh and Rohilkhand Railway Company (O&R Railway) between 1868 and 1888. During this time he was initially in charge of the construction of the Ramganga River Bridge and Lines.

Between 1881 and 1887, Walton was in charge of the construction of the Dufferin Bridge over the Ganges at Benares. The bridge carries rail track on the lower deck and road on the upper deck. The Dufferin Bridge is one of the major bridges on the Ganges and carries the Grand Trunk Road across the river. It has 7 spans of 350 ft and 9 spans of 110 ft long and it was the first bridge of its type constructed in the Indian sub-continent by the engineers of Oudh and Rohilkhand Railway (O&R Railway). The total length of the Dufferin Bridge is 1048.5 metres. It was renamed the Malviya Bridge in 1948.
