Train delay - who is responsible?

As long as you had sufficient connection time, the fact a ticket was sold demonstrates the time to be adequate, you have a valid claim.

Press them and take further if no success.

"What if I am delayed on a multi-leg journey?
If you are travelling with more than one train operator and you experience a delay, it is important that you make your claim for compensation to the operator that caused the initial delay. It is important that you leave sufficient time to maintain connections (including crossing London connections). Compensation will only be paid for missed connections when enough time has been left to meet the connection and you hold a ‘through’ ticket that covers the entire journey."

Were there any Virgin staff at Peterborough you could complain to at the time?

I ask because when Virgin West Coast did this to me and I arrived at Crewe late enough to miss a connection - their Customer Services folks at Crewe got me a taxi to my final destination (on their account) since that was cheaper than the delay repay. It would have been over an hour because of the wait for the next train.

Anyway - I think you are entitled to challenge Virgin again - making clear you are referring to the whole journey and which connecting train you had to take.

Their website states

How does Delay Repay work?
If you arrive at your destination late because a Virgin Trains East Coast service was cancelled or delayed, you can submit a claim.

Their passenger charter uses the phrase "destination station". So as wealdroam says - that's Stamford, not Peterborough.

On Sunday I travelled on the 1800 kings cross to Peterborough train which was due to arrive at 1843, before catching the 1855 Peterborough to Stamford train, due to arrive at 1905. The ticket was an advance with the train times and seat reservations printed on the ticket. I had not split the tickets.
The virgin train from London was 14 minutes late arriving at Peterborough meaning I missed my designated connection and had to wait an hour for the next train from Peterborough to Stamford, which arrived at Stamford at 2011, some 66 minutes later than I should have done.
I submitted a claim to virgin but they refused it as I was only delayed by 14 minutes on their train.
Is this correct?

You are entitled to Delay Repay for a delay of 60+ mins, from Virgin Trains EC.

The connecting train was not late

You appear to be suggesting that a Delay Repay claim is invalid. If that is what you are saying, you are incorrect, but MSE won't do anything about incorrect info being posted here.

martinbuckley - unfortunately that is a risk of using this forum for railway ticketing questions; there are some people here who post inaccurate/misleading information. Fortunately in this case everyone else gave out correct information.
