Quote: Dave Lister "I once travelled using a Travelcard that was bought with a train ticket. I was told that it can only be used on Underground services. This went alongside not working in the ticket barriers at Waterloo (the attendant let me through) and having to follow someone through when I got to Twickenham.'"
I've only ever bought them with the intention of using them on the tube.
In my experience, ones bought through the company (via the trainline's business service I believe) tend to work in the barriers, but ones bough from Virgin trains tend not to. Meh.
