I'm booking a two singles to do a round trip. Preston to Aberdeen. 1 adult disabled persons railcard. Visiting a friend so flexible with dates and time of travel. (However catching X2 Formby to Preston and vv and would prefer to use my concessionary travel pass) Have used TPE mixing desk. Not find any: LNER and Connections advance tickets(I assume via Leeds) TPE and Connections advance tickets (expect for an occasion very early start) No Caledonian Sleeper Advances for the seated coach. I can find a handful of VTWC and Connections Advances. Although only about 2 or 3 departures daily they are consistent in availability which is good. It is exactly the same for the return leg except for I can only find 1 advance ticket option a day. That's a VTWC and Connections Advance (onto LNER) leaving in the morning. Again its consistent but only one choice! Something seems seriously wrong here for such limited choices given all the flows. I've entered in loads of dats from next week until the end of April and am getting very similar results. I'll have a play around with TrainSplit later to see if that gives more choice. I have changed the starting point to Liverpool and similar lack of choice. One final thing, for the VTWC and Connections ticket the change is at Edinburgh. On the way up its not the longest of connections given the size of Waverley. Both trains stop at Haymarket. If I want to force a booking engine to have me change trains there do I have to use TrainSplit?
