As I walked my bike through the station to the bike parking, observing the requirement to dismount and behave without reproach and listening to the various warnings about antisocial cycling, cycle parking, looking at bikes, thinking about bikes - a ScotRail employee came to tell me sharply to switch my (dynamo) lights off as they confuse the guards.
I think this is daft and indicative of a general culture of disproportionate cyclist scrutiny which is everywhere in the station and on trains in general.
Is this a reasonable request - I can't really tell. It felt daft at the time?
