The Gartell Light Railway is a privately run narrow gauge railway located at Yenston in the Blackmore Vale, south of Templecombe, in Somerset, England.

It operates a 2 ft (610 mm) narrow gauge railway running for 3⁄4 mile (1.2 km), partly along the track of the old Somerset and Dorset Joint Railway.

The railway is controlled using a comprehensive signalling system operated from two signalboxes - Common lane and Pinesway Junction.

Both signalboxes control a mix of semaphore and colour light signals with mechanically operated points.

[2] The railway is open to the public on selected dates through the year when it normally operates an intensive 3 train operation with departures from Common Lane station every 20 minutes through the day between 10:30 and 16:30.
