Rail strikes: How you'll be affected in Peterborough, Stamford and Rutland
Train drivers are refusing to work overtime for six days
Disruption to rail journeys are expected in many parts of the country this week as train drivers refuse to work overtime for six days.
Aslef announced last month that its members will withdraw non-contractual overtime, known as rest-day working, with 16 of the country's 35 rail operators from Monday July 3 to Saturday July 8.
The action could impact visitors to the first week of the Wimbledon tennis tournament.
The RMT union has also scheduled further strikes for the following dates:
Thursday 20 July
Saturday 22 July
Saturday 29 July
Which train lines are affected?
Avanti West Coast
Avanti West Coast has said it is currently looking at the impact the RMT strikes will have on its services and will have "more information" for its customers soon.
It said it plans to run its normal timetable during the Aslef action.
On previous occasions, it said that customers who booked tickets to travel on strike days before industrial action was announced could claim a full fee-free refund from their point of purchase.
C2C
The website states if your journey is delayed by over two minutes, you will automatically get a delay repay if you travel using a c2c Smartcard.

Chiltern Railways have put out a detailed announcement about what to look out for when travelling.
It said during the Aslef action, trains will be busier than usual, and there will be changes across the network's timetable.
It has also advised customers to "check before you travel".
Due to the Aslef action, the railway has said there will be a limited service in operation between 3 July and 8 July.

It has also advised passengers to check before travelling.

"More information including timetable details, journey planners and ticketing/refund advice will be updated as soon as possible," it added.
Greater Anglia
Greater Anglia has said services will start later the next day - after each RMT strike - as a "knock-on" from the walkouts.
It has asked customers to check back later on its website for more details.
Great Western Railway
GWR has said that on RMT strike days, there will be a reduced and revised timetable, and warned many parts of its network "will have no service at all".
It also said during the Aslef action "short of a strike and the days after RMT strikes, services could also be affected by a limited number of short-notice cancellations and alterations".
It added: "The Night Riviera Sleeper service will not run in either direction from Sunday 2 July until Friday 7 July, resuming on Sunday 9 July."
Customers are advised to check before they travel.
If you purchase tickets for the strike days but do not end up travelling, you can claim a full refund or amend the ticket.
GTR
GTR, also known as Govia Thameslink Railway, is the UK's biggest railway franchise and operates Southern, Thameslink, Great Northern and Gatwick Express.
Between 3 July and 8 July, there will be an amended timetable, with fewer services running.
The companies said: "Services will be busier than usual. It's likely you will need to queue and you may not be able to board your chosen service. You should allow extra time for your journey."
Gatwick Express services will not run. Gatwick Airport will still be served by Southern and Thameslink.
LNER
London North Eastern Railway has said: "We are reviewing this RMT announcement and evaluating how this will impact our timetables and your journeys."
Northern Trains
The railway operator has said it is looking into the RMT strike dates and how exactly the industrial strike will affect its services.
"We do however expect disruption across these days," it said on its website.
The Aslef action will see "some services to start later and finish earlier than usual".
Southeastern
The company has said if RMT's strike action goes ahead, then "it is likely that we will only be able to run a limited service on these dates 20, 22 and 29 July".
With regards to the earlier Aslef overtime ban, Southeastern said it was "working to understand if this will affect our services".
The company said it will update its website accordingly with more information in due course.
South Western Railway
In relation to the RMT strikes, South Western Railway has said customers should expect severe disruption and should consider changing travel plans now if possible.
"We are assessing the impact on services and will publish information for customers as soon as possible," it added.
With regards to the Aslef action, South Western Railway said on its website: "We have decided to provide greater certainty for our customers by creating an amended timetable that we have a high degree of confidence we can reliably and safely deliver each day." The service summary was from 3 to 7 July.
Transpennine Express
The railway is yet to update its website on the latest strike action plans.
West Midlands Railway
West Midlands Railway said during the RMT strikes, it will be running a reduced timetable on these dates and some routes will not be served.
It said it would update its timetables on the strike days in "due course".
During the Aslef action on 3 July to 8 July, West Midlands Railway said it "will continue to operate to our full advertised timetable".
"A small number of services may be subject to late-notice cancellation or amendment during this period and passengers are advised to check their journeys before travelling."
Negotiations
It is understood that there have been no negotiations between the union and the rail operators since the action was announced on June 19.
Mick Whelan, Aslef's general secretary, said at the time: "Once again, we find ourselves with no alternative but to take this action.
"We have continually come to the negotiating table in good faith, seeking to resolve this dispute.
"Sadly, it is clear from the actions of both the train operating companies and the Government that they do not want an end to the dispute.
"Their goals appear to be to continue industrial strife and to do down our industry.
"We don't want to inconvenience the public.
"We just want to see our members paid fairly during a cost-of-living crisis when inflation is running at above 10%, and to not see our terms and conditions taken away.
"It's time for the Government and the companies to think again and look for a resolution."
Disruption
A spokesman for the Rail Delivery Group responded: "Aslef's leadership continues to disrupt customers' travel plans.
"They rejected a fair and affordable offer without putting it to their members which would take average driver base salaries for a basic salary for a four-day week without overtime from £60,000 to nearly £65,000 by the end of 2023 pay awards.
"Train companies will work hard to minimise the impact of the overtime ban but the impact of Aslef's action will vary across the 16 train operators and customers are advised to check their travel plans before setting off.
"We ask Aslef to recognise the very real financial challenge the industry is facing and work with us to deliver a better railway with a strong long-term future."
