If I am denied access to my bike (and thus i am unable to prepare it for alighting) until the train has arrived at my station, then I will ensure, from the platform, that the train waits until I am granted access, with no shame or embarrassment whatsoever. However, once I have been granted access, I then still have to retrieve my bike, meaning that I am inside the train, which may by now be late if staff are not in position on its arrival. This then leads to the risk of the train being dispatched with me still on board.
What a shambolic set up - yet another example of poor design leading to problems. A properly conceived bike area should have been included from the outset, with no driver distraction potential or anything else which would impair the operation of the railway. I am a cyclist, but whatever one thinks of bikes, their popularity as a form of transport has been growing rapidly for decades now and there is no excuse for the apparent 'afterthought' facilities that modern trains have.
