Myself and some others had experience of anti-bike from the ticket inspector on South Eastern trains, which I am happy to say is probably the only time I have encountered it from that train company.
A great bit of design from their new trains are the areas designed for bike storage as there is now a safety belt which can be strung and locked around them. When we boarded at Polegate there were already 2 on there but we managed to fit 3 bikes on there (plus attaching some bunjees to keep them together) without impeding the corridor. Cue ticket person saying 'theres too many bikes on there' and we replied rather forthrightly that there was not. Then an elderly couple next door to the bikes started saying 'bikes are dangerous' to which Jane (from this parish) turned around and assertively asked them 'these bikes are perfectly safe' or something similar.
FFS - its the week-end, the weather is good and people want to cycle around the countryside. You would have thought that logically there will be cyclists wanting to get out of London and then make the return trip, therefore make for provision for it instead of criticising them when they board the train!
