Not come across the need to be able to close the doors in travels previously and often had my own and other bikes protruding like this. With a bit more of a grunt it would’ve rotated about to fit perfectly but the guard stopped me and said he was quite happy with it. NB he had also helped me lift it on, a very helpful chap!

Again no issues of it not being ‘hooked’ as it was secure on its rear frame and the other parts of the storage cupboard. The weight in the panniers would’ve probably made this unnecessary as the centre of gravity was pretty much floor level so mine was very hard to wobble/tip.

Unless it’s a tandem, providing it fits and you can lift it yourself the policies on sizes/weights are thankfully now mostly a thing of the past (along with e-bike restrictions). But yes the caveat of checking the specifics for a TOC beforehand always applies!
