This is a great opportunity to ask Howard Collins anything about your Tube journey experience. To get involved you can email questions to email@example.com or Tweet them to @LonTravelWatch.
The meeting is public so if you're around for an hour from 11am on 22nd March 2011, feel free to go along. It's being held at London TravelWatch's offices.
Jo DeBank from the organisation said "I’ll be ‘live tweeting’ the Q & A session and we're happy to take questions in advance by email too. We cannot guarantee that all questions will be answered on the day, but we will try to ensure that all questions are answered and responses posted on our website".
