I was half-thinking of travelling from Yorton to Stoke-on-Trent and return on Thursday for the hell of it (and so I get to use a request stop and my nearest station as the crow flies, according to Bing). I can find an Anytime Day Return for £12.30. But if my return train gets delayed and I miss my connection at Crewe, what if I wanted to go to Shrewsbury instead of Yorton (further, but got more frequent trains; if I miss my train to Yorton I would like to be able to get hte next train to Shrewsbury which does not call at Yorton if I can get an excess)? (I live fairly near both Yorton and Shrewsbury and usually use Shrewsbury, but Yorton is served only two-hourly). Would they sell me an excess at Crewe station? I can find an Anytime Day Return of £16.40 from Shrewsbury to Stoke-on-Trent; would I get an excess for the difference between this and the £12.30 from Yorton to Stoke-on-Trent (£4.10)?
