The original design of the WHR station at Crianlarich would have allowed through running from Glasgow to Oban via the West Highland, but this was not implemented. The Caledonian Railway suggested a joint station that would have allowed both routes (from Stirling or from Helensburgh) access to both destinations (Oban and Fort William, and there was a proposal that passenger trains from Central Scotland by both routes should combine at Crianlarich and then divide with portions for both Oban and Fort William.
