I'm sad to announce that @uktrains - my side-project for the last two and a half years - is closing down today as the BBC withdraws the Backstage services which powered most of the tweets it published.
The service operated for approximately two and a half years, was followed by almost 20,000 people at peak and issued over 85,000 travel tweets. [Updated: Previously I'd used underestimates of 10,000 followers and 50,000 tweets]
I'd like to thank all those who supported it - especially those who submitted crowd-sourced reports and wrote about it. I'd also like to acknowledge the enthusiasm of the team at National Rail Enquiries who were keen to use the lessons learned in the creation and growth of their set of official Twitter accounts providing disruption alerts.
There's more details and a comment on the work still to be done on the service's Wiki. I've also created a Twitter list of 'tweeting train companies' to track those also offering customer service via social media.
