CANCELLED rail strike against Avanti West Coast in addition to the ongoing action

Thank you, Nigel. What are the implications of the overtime ban? I have tickets for LNER trains on July 26 (Edinburgh to Darlington off peak tickets with seat reservations on the train leaving at 17:00) and July 30 (Darlington to Kings Cross leaving 9:27). Am I correct in thinking the July 26 train could be canceled due to the overtime ban? I am flying into Edinburgh on the 26th (from Lerwick) and might be able to make an earlier train, but I could also be delayed getting in and need a later train.

LNER will update their website in due course when they know what is happening.
At the moment there simply is no news on this to report.
You would imagine the impact on the first week after 2 July would be announced in around a week's time. At least then the likely extent will become a bit clearer.
But currently you just have to wait.
The same is true of Avanti- tickets are removed from sale until the impact can be assessed. For them an announcement will probably come in around 10 days time.
For EDI to Darlington both Cross Country and TPE will be operating as normal (unless more widespread action is announced) so there are other options.

Overtime bans lead to shortages of staff availability and potentially cancellations eventually although these will tend to be spotty.

Thanks so much for the responses. I will try to sit tight. (Not my strong point.) I assume if I have to take a train with another train company, I will have to buy new tickets, correct? Which would not be a big deal because I can get a refund on any canceled train.

Whether you have to buy new tickets depends a lot on circumstances. If you have bought a fare other than an advance fare - a more expensive walk up and go fare -it is valid on any operator. If it is an advance fare LNER or whoever may announce what is called a " ticket easement". Basically an agreement to relax the rules and allow use either on any train of theirs (not the specific one booked) and/or on other operators.
That will, or will not, come in due course.

Ultimately the train companies don't want the hassle of refunds, nor do they want people making a modal shift to car, air or bus so they will do all they can to keep you on the train.
From your point of view, don't be impatient. Don't do anything before all the facts are known, and don't be selfish with making multiple bookings. That is depriving others of the extra seats and cheap fares you have booked.

Thank you again for the answers and explanations. It is very helpful.

In one case, I purchased an advance ticket. In the other, I got an off peak ticket. I will wait patiently (or possibly impatiently, haha) until more is revealed. In no case will I double book. I had thought of getting cheap bus tickets as an insurance policy, but rejected that because it would potentially deprive someone else of a seat. I would only purchase new tickets if my existing one became invalid.

So how do you find out about these strikes? I've been keeping an eye on the National Rail Industrial Actions webpage since we have a half dozen train journeys in July. Neither of these strikes appear on that page, so obviously there's something else I should be looking at in addition. Thanks.

The think is they aren't strikes. They are action short of a strike. As said above the only answer currently is to haunt the LNER website.

I suspect it'll be like I currently have on my local line, where there is no official industrial action at all, but different trains are being cancelled each day due to drivers not presenting for work as they are unwilling to work overtime.
You can phrase that however you like but trains are being cancelled or terminating/starting short routinely at a maximum of 12 hours notice. Around here we just have to live with it.

Just announced- there is an overtime ban across all 16 affected train companies from 3 to 8 July- Transport for Wales, Scotrail, London Overground, Merseyrail, Lumo and Grand Central not affected.

Update- Avanti have now opened bookings for 2 July- there is no impact of this strike in the published timetable, as it has been called off, so a normal service is operating that day.

thanks - I'll update title. Hadn't heard.
