The validity of the ticket and the difficulties you might face using it are not one and the same. Rail tickets are generally interavailable on the underground between Kings Cross and Highbury, but then the same applies to Kings Cross and Moorgate and plenty of people have trouble with the latter.I guess my concern with it is that I've never seen a valid routing from a London Terminal station begin with an underground journey and (again a well-worn topic here) the ticket doesn't print with a Maltese Cross, which I'd guess would lead to gateline problems.
There is never a question of whether a ticket is 'invalid' if it is offered by a journey planner in conjunction with a particular ticket. The fact that the two are offered together means that, if you buy the two together, you are contractually entitled to travel as per the itinerary, and are entitled to damages for any losses or costs you incur if you are, for example, denied entry with that ticket at King's Cross.Just trying to work out the best ticket for this (flexible day return on Saturday, network railcard). Trainsplit will offer me the following:

I'm not going to use a ticket that's invalid so can someone confirm that this isn't valid? Surely this can't be used from KGX on a London Terminals ticket.
If it won't work the barrier, what ticket *should* I buy if I want to avoid problems with that? Is it just a Zone 1-6 - Southend Central ticket? Pretty annoying if so as it's priced at over twice as much.
Yes. As long as you are breaking your journey in a valid matter and respect the minimum connection times it doesn't matter what ticket(s) you use.Thanks - and this is a question I really should know the answer to already - but am I covered for a connecting transfer from SOC-KGX onto my train to Leeds on that ticket since I'm breaking my journey early?
To do that you will almost certainly need a different ticket - one that's valid on HS1 - and you'll need to transfer between the two stations at Stratford, either walking or by DLR, allowing probably 15 minutes or more. However, the easiest journey would surely be to use the underground from Kings Cross to Liverpool Street and c2c from there.Actually - just realised I can go to/from St Pancras via HS1 & transfer from Stratford Intl to Stratford, so avoiding the underground altogether anyway.
Is the ticket valid on the Underground between Moorgate and Liverpool Street? It's valid using the interavailability in the Kings Cross - Moorgate - Finsbury Park triangle (with the usual bar on most intermediate stations), but to Liverpool Street?To do that you will almost certainly need a different ticket - one that's valid on HS1 - and you'll need to transfer between the two stations at Stratford, either walking or by DLR, allowing probably 15 minutes or more.

No, but as the OP is coming from Yorkshire to London they may have a ticket already that will cover travel from Kings Cross to Moorgate. Regardless of that, I wonder if it is worth making the journey more complex than necessary to save a couple of quid and risk missing the last train back to Leeds.Is the ticket valid on the Underground between Moorgate and Liverpool Street?

Yes. HS1 is no different to any other route from a routeing perspective.AIUI a ticket is valid on HS1 if a mapped route unless the ticket has a not HS1 restriction - is that not right? There's no such restriction on this ticket and booking engines unproblematically offer itineraries.
Unless I am missing something, the only condition is that you must travel via Barking - and if you use a c2c train between Stratford and Southend Central you will do that.
It doesn't appear to be a mapped route - Barking to London Group is mapped on map TS which takes you into Liverpool Street or Fenchurch Street. There are no other mapped routes.AIUI a ticket is valid on HS1 if a mapped route unless the ticket has a not HS1 restriction - is that not right?

The RSP data for valid Terminals shows only the two that you expect.It's marginally surprising that Kings Cross is a valid "London Terminal" for Southend Central. You might expect that it was only Fenchurch Street and Liverpool Street.

The route is a permitted route due to the shortest route rule; it's within 3 miles of the shortest route.It's marginally surprising that Kings Cross is a valid "London Terminal" for Southend Central. You might expect that it was only Fenchurch Street and Liverpool Street.
That data source is just an interpretation of what's valid though, and not one that everyone will agree with.The RSP data for valid Terminals shows only the two that you expect.

I made no such claim.The London Terminals Mapping feed plays no part in establishing the validity of a route.
