 Parson took a combative line when this was queried by the Board of Trade, and this resulted in their obtaining an injunction against use of the unapproved track.On 18 March 1854 the line reverted to mixed gauge single line, and Parson refused for some time to comply with the BoT requirement.At length the second line was reopened on 20 March 1855 when a broad gauge rail had been installed, and the line was doubled as far as Campden.
