Firstly, let me apologise for my recent absence, but I have been suffering from the effects of the heaviest cold that I can remember.
Secondly, let us remember that it is the Edinburgh and Glasgow Railway, not the Caledonian Railway Main Line, that we will join after leaving the Scottish Central Railway. Therefore, after Greenhill Lower, we would have taken the line that led to the Edinburgh and Glasgow Railway, meaning that the posting of Throsk (which was on the Alloa Railway) needs to be struck through.
