The SNP has a much better record on rail reconstruction than the rest of the UK (London excepted), Larkhall. Alloa, Airdrie to Bathgate and the Borders Line are the best examples, pressure is still on to add to these lines but the cost of electrification of just about everything in the central belt just now will probably mean no reopened routes in the near future. Possible future re-openings include Grangemouth, Methil and St Andrews, with the extension to the Borders line still a possibility
