Cost of a restored / deviated Cheltenham to Kingham railway
Estimate that was referred to during June 2013 by Gloucestershire County Council was for a double track electrified railway used by a high frequency London commuter service.
But the restored Cheltenham – Kingham – Oxford railway would be single track and diesel operated

A more accurate comparison could be with the proposed re-opening of the railway between Bere Aston and Tavistock on the edge of Dartmoor, with a price tag of £150 million for 5.5 miles of single – track railway line beside a cycle way, to be operated with two coach diesel trains.

Using this cost per 5.5 miles plus cost of stations, structures and earthworks as a basis for calculation…
A “ball park figure” for the Cheltenham to Kingham scheme starts at £687 million plus cost of structures and earthworks

A recent comparison could be with the proposed re-opening of the railway between Stratford Upon Avon and Honeybourne, with a price tag of £228 million for 9 miles of single – track railway line at least partially beside a cycle way, to be operated with two or three coach diesel trains. Extensive tunneling is required at Stratford Upon Avon, extensive bridge repairs are needed along the route and track replacement is required between Long Marston and Honeybourne.

Using this cost per 9 miles plus cost of stations, structures and earthworks as a basis for calculation…
A “ball park figure” for the Cheltenham to Kingham scheme starts at £715 million plus cost of structures and earthworks.
