Proposed strike dates:

Monday, 22 April Monday, 29 April Monday, 6 May

Aslef announced on Wednesday it had given notice of three 24-hour strikes from Monday 22 April.

Both sides have put forward proposals but no agreement has been reached.

Meanwhile, tourist chiefs have raised concerns that the strikes, planned for the May Bank Holiday could cause havoc across the region.

One of the proposed dates is 6 May - one of the busiest weekends of the year.

It is feared that next month's one-day strike could seriously effect the economy and stop people from visiting north east Wales.

Strike action could effect Llandudno

Esther Roberts from North Wales Tourism said the strike would be damaging: "We would expect thousands of visitors during the weekend, a strike would deter them from coming.

She added: "This is bad news for an industry just getting back on its feet - this is something we really do not need."

The train operators and union chiefs have said that further negotiations have been scheduled.

Talks broke down last week as passengers were disrupted by the third strike in seven days.

Unions have staged three 24-hour strikes

An Aslef spokesman said it was hoped a deal could be reached to end the dispute, which began over the suspension of a driver for alleged safety breaches.

First North Western is anxious to resolve the industrial action, which has proved costly and disruptive to services.

The train operator carries 8,000 passengers on the north Wales coastal routes every day and operates the biggest train service in north Wales and the north west of England.

The first strike is not until Monday week and there is time for the dispute to be resolved

"We are still hopeful of coming to an amicable agreement - neither side wants strike action - and hopefully some deal will be reached," said a spokesman for First North Western.

An Aslef spokesman said the threat of further action was some time away.

"The first strike is not until Monday week and there is time for the dispute to be resolved.

"Hopefully, First North Western will now focus on a settlement."

Aslef had already warned of further strikes earlier this week.

The rail unions have stressed the dismissal needs to be fully addressed before they will call off the action.

The company claims the driver had passed two red lights and was caught exceeding the track speed limit by 10mph.

Long-running row

First North Western has been providing a limited replacement bus service on some routes on strike days.

Virgin Trains services between Holyhead and London Euston have also been hit, because the company employs First North Western drivers.

Monday's walkout was the third in a week - following stoppages last week on Tuesday and Friday.

Aslef and RMT members are also concerned about a long-running row over the downgrading and dismissals of a number of its members.
