Maps of the Caledonian Railway
The Caledonian System stretched from Carlisle to Aberdeen and from Oban to Edinburgh. This network included, as well as the lines owned,the lines leased and/or worked, the two largest of which were the Callander & Oban and the Lanarkshire and Ayrshire railways. An aspect not clearly identified on most maps is the 52 chains of North British rails on which the Caledonian Railway exercised running rights to gain access to the Aberdeen road from the Motherwell to Glasgow line of railway.
