Are there any reasonably large and busy stations left (let's say a minimum of 4 regularly utilised platforms) which have no physical barriers or prohibitions to accessing any of the platforms nor any discouragement from freely accessing any public part of any platform?
Many reasons have been given for the need to control access to platforms e.g. revenue protection, allowing trains to be cleaned between journeys, preventing trains from being boarded during attaching/detaching of units, preventing random folk from wandering about who might cause harm to themselves or to others etc. They may well be valid reasons and I'm wondering why they seemingly were not perceived to be sufficiently valid in the days when Open Stations were seen to be the way to go.
