The largest rail strike in decades is taking place June 21, 23 and 25, with ScotRail urging customers not to travel if they can help it.
Significant disruptions lie ahead, with just five ScotRail routes operating during the three-day strike.
ScotRail has confirmed that passengers are entitled to full compensation if they choose not to travel during the industrial action.
Rail passengers have been asked to consider alternative options and travel only if they "really need to".
The firm has warned customers of disruptions extending to the days between strike action.
ScotRail confirmed in a tweet there will be a "slight knock-on effect" on Saturday, June 26, as well.
It comes as workers on 13 lines, plus Network Rail, are walking out over pay, conditions and cuts to 2,500 maintenance jobs.
Whilst the industrial action will not directly involve ScotRail staff, it will severely limit the government-owned operator's ability to provide services.
The strike will involve Network Rail staff that work in 'safety critical' roles, making it impossible for ScotRail to run the vast majority of its services.
Customers' rights to compensation appear to have been tweaked to be slightly more generous for season ticket holders.
Transport Secretary Grant Shapps confused things a little by claiming the process would be automatic when - as far as we can tell - it's not, but there are still refunds for delays.
Here's what ScotRail passengers will want to know.
Can I get a ScotRail ticket refund for the rail strike? What about a full refund?
Yes. You can claim a full refund if you choose not to travel during the industrial action and the standard £10 administration fee will be waived.
If you hold a valid ticket dated for the strike days, you can use it to travel the day before or the day after.
Customers can request a refund on any ticket type using the operator's online refund request form or by visiting a ScotRail ticket office, if that is where you purchased your ticket from.
Can I be compensated if I travel during the strike and get delayed?
If you must travel and are delayed for 30 minutes or more, you are entitled to Delay Repay compensation, but claims must be made up to 28 days after your journey.
Here's how much compensation ScotRail travellers will receive from Delay Repay:
| Length of delay |
Compensation |
| 30 to 59 minutes |
50 percent of the cost of your single ticket or 25 percent of the cost of your return ticket |
| 1 hour to 1 hour 59 minutes |
The full cost of your single ticket or 50 percent of the cost of your return ticket |
| 2 hours or more |
The cost of your single or return ticket |
What if I have a season ticket?
If you hold a season ticket, complete the online refund request form and ScotRail will calculate the refund amount.
For the duration of the current temporary timetable and the strike between June 21-25, season ticket passengers whose journey has been cancelled are able to claim compensation through the Delay Repay scheme here where they should select 'Did not travel' when submitting a claim.
Alternatively, you can choose to surrender your ticket on the online refund request form and the £10 administration fee will be waived.
Will strike refunds be automatic for season ticket holders?
At the moment it doesn't appear so, despite what Grant Shapps has said.
The Mirror reported the Transport Secretary's claim that he's moved to help make it an automatic process to remove the inconvenience for passengers.
But his claim was contradicted later by sources who suggested season ticket holders will have to apply through the Delay Repay scheme, as they usually do.
There does, however, appear to be some small differences for season ticket holders.
Under a one-off arrangement, it appears season ticket holders will be allowed to claim 100 percent of the usual Delay Repay compensation if they choose not to travel on the three strike days - regardless of whether their train is actually cancelled.
This arrangement will only apply to the days of the strike itself, not the days in between when trains will still be disrupted.
