The beinspiredbytime.com site, created by digital agency glue, aims to support the proposition that trains are the perfect place to relax and think. Visitors are invited to post their ideas or to comment and vote on other people's.
To incentivise users to add ideas, there will be a prize each month for the best idea, culminating in a grand finale where the best of the monthly winners will be chosen at the end of the campaign.
"The aim of our new site is to encourage customers to share their ideas. By so doing they can communicate and interact with us on their own terms, in a way that they find engaging," said Rachel-Linden Brown, new media manager at Virgin Trains.
Virgin Trains has also partnered with Guardian Unlimited in a deal brokered by MG OMD to create a co-branded microsite encouraging users to write their own short stories.
The microsite, which will run for eight weeks within Guardian Unlimited's Books section, will feature four short stories from up-and-coming writers for users to download.
There will also be a guide to how to write short stories and a competition to inspire and encourage users to upload and share their own with other users for a chance to win £1,000.
