“The upper portion of the old Plymouth and Dartmoor Railway was taken over by the Princetown Railway, which opened a passenger line on 11 August 1883. This was standard gauge and connected with the Tavistock line at Yelverton Siding, but passenger trains on the branch used Horrabridge station as the connecting point until 1 May 1885, when Yelverton passenger station opened.
Trains and rolling stock running from Plymouth to the Princetown line used the narrow gauge rail, laid for the LSWR, as far as Horrabridge” (source: here).
“HORRABRIDGE [GREAT WESTERN RAILWAY] opened 22 June 1859 (Tavistock 21st, 24th); acted as junction station for Princetown branch until Yelverton opened; closed 31 December 1962**” (source: here).
