yeah - I recommend having an overheight car (eg roof box) - then you get to ride in the high ceilinged carriage used by large passenger vehicles such as busses ... no extra cost, very roomy sense of space and smooth motion

btw trucks (as opposed to passanger carrying busses and coaches) are unhitched and take different trains with the drivers all in a dedicated people carriage next to the loco - guess they must have known about truck fires and separation of people from goods
