The Callander and Oban Railway is a historic Scottish railway, part of which is abandoned and part still in use.

 

In July 1923, The Railway Magazine carried an article about the Callander & Oban Railway (C&O) written by GF Gairns.

 

Gairns commented that the C&O constituted the third of the three great mountain lines: the Perth-Inverness line of the Highland Railway; the West Highland Line of the North British Railway; and the Callander & Oban Railway (including the Ballachulish Extension).
