A new free service from First Great Western designed to help rail commuters adjust their journeys more efficiently when faced with service disruptions, is introduced this week.

The JourneyAlert system, will text or email customers with any cancellations, alterations, or route disruptions to their train services. JourneyAlert will provide information about delay causing events - such as flooding on the line, track infrastructure problems and resulting disruptions.

The 'intelligent' web based system will allow commuters to receive personalised text messages and emails that will alert them to any changes to their regular services, as well as provide further updates on request. The facility can be set up by the user to tell them about service changes before leaving the office or home.

Subscribers need to register with the system and choose the number and type of alerts they wish to receive. Each part of a journey needs a separate alert setting up.

JourneyAlert customises route information and complements existing delay information presented via First Great Western's web site and station departure boards.

Paul Higgins, Customer Information Manager, First Great Western, says: 'We know that sometimes things don't go as planned, so this free service means we can let our customers know what's happening so they can make any changes to their journey plans with information readily available.'

Journey Alert is now available and customers can register via the First Great Western web site FirstGreatWestern.co.uk where sign-up and route choice options and details will be displayed.

The service is free, however it is possible that mobile providers may charge for receipt of texts: the delivery of emails to mobile devices can incur charges from providers.
