The internal guidance is that split points can be ignored, and the through journey is what counts for the purposes of determining what "reasonable routes" can be used. But as mentioned multiple times in this thread, the policy really needs to have clear rules publicised to avoid potential disputes with frontline staff who haven't read or received a briefing.
I agree. There is a lot of scope for staff to be stuck on the old world on a lot of this.
This announcement doesn’t seem to deal with delayed trains unless I am mistaken? That is a point that definitely needs work as for many people a delayed train is as bad as a cancelled one and there is definitely scope for people misinterpreting this announcement.
I would favour a very simple rule. If your train is delayed by 15 minutes or more at the station you are catching at, you can catch any other train to get to your destination that ends up leaving before your train.
I would not distinguish between local and longer distance journeys.
The reason I choose 15 minutes is because that is when the railway already thinks you should be compensated in the majority of cases.
If you are trying to get somewhere for a specific time, the best compensation is an alternative solution that gets you there as close to the original time as possible.
The vast majority of delays are under 15 minutes so this only catches the more extreme examples. It also seems to be the magic number where the delay gets worse and worse and can turn into ‘your train is cancelled full stop’ or ‘your train is running so late it is going to stop short of its destination’ and those are two of the biggest wind ups on the railway. Allowing people to take a chance on an earlier service of another operator or another route is to be totally reasonable.
If something is not done on this there will definitely be passengers who (quite rightly in my view) view a large delay as equivalent to a cancellation and expect to be able to work around it.
