I'm thinking an enquiry with a via point would really be a composition of two journeys, and the composition needn't have the 16-change restriction. Nevertheless, I would be interested to see the journey you're referring to.

NRE suggests a journey with 11 changes for Yarmouth, Isle of Wight [YMH] to Ulceby, N. Lincs [ULC] on Sundays departing at 10:20am. Does anybody know of a logical NRE journey with more than 11 changes (including overnight)? Also, would there be any likelihood of a logical journey ever having...

Typing a station code now brings that station to the top of the list. I'm using ATOC data for links between stations, which appear to be the same data used to plan journeys on NRE and other sites. Journeys are timed as Indigo2 describes. An option to adjust walk/connection times will be added in...

It's been a while, but I've totally rebuilt the journey planner (www.gbrail.info). It can now return every optimal journey between two stations for any date (currently limited to next Monday while testing). Optimal means quickest per number of changes. Minimum change times are respected...

Thanks for all the helpful and insightful comments - they have been duly noted. Lots of things to fix, which will take a while, especially trying to diagnose some of the more inexplicable journey suggestions. In the meantime, feel free to message me about anything.

Some sort of via facility will be coming, although I'm thinking of showing only sensible/valid choices for the origin and destination entered. I'm unable to reproduce the autocomplete issue. Could you message me your OS, browser version, and a more detailed description of the behavior, please...

I'm glad you're finding the information useful. Yes, the planner is a bit too keen to get on a train - this will be the first thing for me to fix. A workaround is to specify an arrive time instead of a depart time.

That is one of my intentions - to present journeys that respect official connection times while pointing out other, more risky routes for the more spritely, informed, or adventurous (along with a strongly worded warning, of course). It could also give an official journey and still advise of...

Indigo2: The planner will recognize Changes En Route in its next iteration. And thanks - I strive for simplicity. dooton: I see that too and the route it gives certainly makes no sense as there are (several) quicker alternatives. I shall investigate. Good luck with your app. For me, just...

Yes, DCH to RBS times out despite DCW to RBS being found rather quickly, which seems to defy logic. There is much tweaking to be done. I've tried to incorporate minimum interchange times for each station from the Master Stations Name CIF file, but the routing engine I'm using chokes when I try...

Working out QRB to WCK etc. seems to take the planner longer than the timeout limit I'd set (based on the most complicated journeys I could think of - not complicated enough, apparently). Thanks for pointing that out. It's routed for time only. With CLJ to THS (and quite a few others I'm...

I've created a rudimentary rail journey planner based on the ATOC timetable feeds: gbrail.info. I know little about the UK rail system and would be interested in any thoughts, suggestions, ideas, or criticisms. By my checking, it does seem to conform to the Routeing Guide, although I do...

There's a train leaving Penzance at 10:00 this morning (Monday). When does it arrive at London Paddington? NR and thetrainline say 15:21 while Transport Direct and firstgreatwestern.co.uk say 15:43. Which is right and what might account for the discrepancy?

The Google Maps website has been offering transit directions across Britain since earlier this year, with data apparently being supplied by thetrainline.com. However, I find the suggested train routes markedly different from those on other sites, such as nationalrail.co.uk. I'm not acquainted...

Adam, I was interested to find your "ticket splitting" application (mostly from a mathematics and computer science perspective). I see that you intend to offer split ticketing advice for Advance fares. However, from my understanding, a comprehensive comparison of intermediate fare...
