Colonel Holman Fred Stephens (30 October 1868 – 23 October 1931) was a British light railway civil engineer and manager. He was engaged in engineering and building, and later managing, 16 light railways in England and Wales.
Stephens was the son of Frederic George Stephens, Pre-Raphaelite artist and art critic, and his wife the artist Rebecca Clara (née Dalton). He was named after his father's friend and former tutor, the painter Holman Hunt, although the two later fell out.
Stephens was apprenticed in the workshops of the Metropolitan Railway in 1881. He was an assistant engineer during the building of the Cranbrook and Paddock Wood Railway, which opened in 1892. In 1894 he became an associate member of the Institution of Civil Engineers, which allowed him to design and build railways in his own right.
He immediately set about his lifetime's project of operating light railways for rural areas, mostly planned and built under the 1896 Light Railways Act. His first two railways, the Rye and Camber Tramway and the Hundred of Manhood and Selsey Tramway, predated this, but he built the first railway under the Act, the Rother Valley Railway (later the Kent and East Sussex Railway).
The railways were planned, and some later run, from an office at 23 Salford Terrace in Tonbridge, Kent, which Stephens had rented in 1900 and purchased in 1927.
Many of his railways stayed independent of the larger systems created in the Grouping under the Railways Act 1921.
