Unless you're delayed over 30 minutes plus the connection time.
The £1100+ claimant was pictured by the newspaper at Ipswich. The East Suffolk and Felixstowe branches are both hourly. Services towards Bury St Edmunds are hourly with extras. London services are roughly four an hour, I think, with different stopping patterns.
So I think a branch line user changing at Ipswich for London could easily have been delayed both ways by more than 15 minutes most days on a commute for some of the fleet changeover, plus possibly more journeys each day if they use their season ticket to travel short distances on the edge of London, or into Ipswich for an evening out (because they have a season ticket, so why not use it as much as possible?). A few stations like Elmswell lost services while problems with doors were fixed and I don't know if the delays caused by that mean Delay Repay claims.
While 118 claims in 6 months sounds a lot, that only averages about 9 every two weeks so definitely above average but far from impossible for a branch line user during disturbed service. I wonder if GA compared her to the average for all customers or to the average for her branch line.
A delay in one direction or the other each day, some of which need only be 15 minutes is still a lot, but i don't think its as impossible as some people are claiming.
If you live on a branch with a 1tph service and a 5 minute (valid) connection onto the mainline service that is 4tph then a delay of a couple of minutes or more and a busy station can see you miss a service and end up 15 minutes late, if this happens 2 or 3 times per week it would not be unheard of.
Of course, if the next train after the missed connection is a stopper, it might get you there 25 minutes late, and with a short delay itself you may breach that 30 minute threshold, maybe once a fortnight.
On the return journey, your 4tph service might have a similarly short but valid connection onto your 1tph branch line, a delay of a few minutes here will see you miss your connection and have to wait 1 hour for the next one, if this happens once per week it would again, not be particularly surprising, twice would not be unheard of for particularly unreliable services. We regularly see specific services with arrival within 5 minute records of less than 20%
So, 2 or 3 short delays on your morning connection per week.
1 delay on your way home per week,
1 delay per fortnight of your train in the morning
It's quickly working its way to 4.5 claims per week without trying too hard.
If they use their season ticket to go to London every other Saturday to see their sister and it is late once a month then we start to get there very fast.
I have done a fairly solid month of claims 5 days a week for consistently bad service where missed connections are involved in the past, with another operator.
