I have a folding bike which I use for commuting to work. Whilst entering Harrow & Wealdstone station the other evening, I was told by a member of staff at the gates that I would have to fold my bike as it was 'peak hours'. I understand that non-folding bikes are not allowed on trains during peak hours, but I don't understand why I needed to fold my bike before entering the station. I use the station every day and this is the first time a member of staff has said this. Is there any truth to this rule? Harrow & Wealdstone is not a major terminus and not a particularly busy station, so I don't understand it.
