When I work in the Farringdon office, I used to catch the 07:50 from Horsham to Three Bridges and change to the 08:10 Cambridge service which took me to City Thameslink. I have noticed recently that this service no longer exists and the 08:10 only goes as far as London Bridge. Is this a permanent timetable change? I guess I could use that service and a folding bike for the final couple of km to the office.
