Hi I travel from Spalding to Minffordd every so often and have never quite managed to get my head around some of the issues with fares, partly as there is the option of taking the Ffestiniog Railway to Blaenau Ffestiniog first, so there are two possible start points. I have a few questions: I was surprised to find my open single from BFF to SPA was valid for two days - is there any way to predict when this will be valid for one day/two days? if I travel on several advance purchase fares linked together what happens if one of them messes up the others? what about if this means I miss the last train of the day part way along the journey? is it possible to travel out via Mach and back via Llandudno Junction on one return ticket (about a week later)? I know this is rather a lot of questions, but I think I have at least managed to work out the routeing for myself!
