Sounds fair.The fact is that a well secured golf bag (secured to the bike frame and the top box) is about the same height and probably at least 50kg lighter than your average pillion passenger.
Blimey. I'd go for the 'look like a prat' on a bike option, rather than look like a prat on a train. You look like a prat for less time, and you wear a helmet. If it is totally safe, as you suggest, what's the problem.This being said it still remains that individual interpretation by myself, other road users and the police may differ. With this in mind I am going to have to look at an alternative. This is a right pain, as bloody stupid engineering work means that the train journey will be almost 3 times longer than it usually would. I could hire a car, but because of internet banking and bill payment I do not have the relevant letters to confirm my address and they do not accept internet print outs.
