Whilst most of the examples above relate to fairly rural areas it is interesting to think about the question from a more modern 'integrated', 'network', 'urban distribution' perspective rather than the historic competitive one.
Gaps like Glasgow Central to Glasgow Queen Street, Bradford Forster Square to Exchange/Interchange, Manchester Piccadilly to Victoria (not via Castlefield!), Sheffield Midland to Victoria and so on suddenly become more obvious.
The cross Glasgow link has been pondered for years, remember that Queen Stree was N.B/LNER and Central was C.R./LMS until nationalisation, so thanks to the rivalry between the two it would need to have been a link form Buchanan Street to Central, unfortunately Buchanan Street was about 100ft higher than Cenral and only a short distance away, so any link would have been a steep incline, in a tunnel, with steam haulage so not practicable. One that comes to mind for me is Largs to Weymss Bay, but again two rival companies operated each branch.
