Minimum Connection Time - Tube to Train

[DeparturesBeck]

A little help/confirmation please regarding minimum connection time when the first part of a journey is by tube.

Ticket type: Advance Single.
Origin: ZONE U1234*LONDN
Destination: Norwich.
Reservation: 14:30 Liverpool Street to Norwich.

Intended journey: Gants Hill to Liverpool Street, then onto Norwich.

The minimum connection time shown on BRtimes.com for Liverpool Street is fifteen minutes. I assume this time is valid for both train-train and tube-train connections, rather than just train-train.

Therefore to find a valid itinerary (which offers me protection in the event of a delay to the tube journey), I simply need to find an itinerary on the TfL website which has me arriving at Liverpool Street by 14:15, right?

Using an example travel date of 23rd April, this would mean that taking the Central line at 13:50 from Gants Hill (arriving Liverpool Street at 14:11) would be valid; whereas the 13:55 departure (arriving at 14:16) would not be valid?

I agree with that.

Unless you are travelling on a Sunday, the 14.30 LST - NRW calls at Stratford. No need to go to Liv St if coming from Gants Hill, and advance fares can be cheaper from Stratford. May be helpful in future.

You are right OP. The 13.50 forms a valid itinerary whereas the 13.55 does not. I was faced with a similar situation roughly two weeks ago when travelling from Manchester to Brixton and back on advances. As long as the minimum connection time is allowed, between tube and train, or vice versa, you will be fine.
