    Was ambling through St.Pancras and gazing up to the roof was wondering which station has the highest roof ?..... not sure if I would count the lower mezzanine as the point to measure from (it not having any platforms and was the beer barrel cellar in the past). Would say platform level to top of ceiling. Most of the main London terminals and the big city stations would be in with a shout I should imagine as most of them seem to be of a similar height.

    Probably Glasgow Central or Queen Street if you start measuring from the low-level platforms.

    The roof at St Pancras is very high and one reason for this is the style of construction.

    At St Pancras there are no tie rods preventing the arch bursting out such as those in the roof at Lime Street for example. Therefore the arch needs to be anchored in something solid like the ground. This means the roof actually does spring from the floor of the undercroft or thereabouts.

    The other factor is that at St Pancras the roof is almost semi-circular so the roof rises high whereas the segmented arch as at Lime Street does not need to rise as high in comparison to the width.

    So as long as you are asking which is the highest roof above the spring of the arch it is almost certainly St Pancras. If it is the highest above sea level then that is more difficult!

    It would also be interesting to know how high the roof of Nottingham Victoria was .... before it was legally vandalised.

    An arch that rests upon the ground may resist spreading by virtue of its abutments. As you point out the arch of St Pancras has no abutments. It is therefore tied together at platform level, which must have given pause for thought when they opened it up during the recent rebuilding.

    If you include Low level platforms, would Liverpool Lime Street be a good shout?

    There's a summary of how it was dealt with on pages 50/51 of a 2004 Arup in house magazine article.

    http://www.arup.com/_assets/_download/download238.pdf

    That's a useful download anyway, for anyone interested in how/why St Pancras turned out the way it did...

    Oh great. Thanks. Pity there's no thankyou button on this forum :D

    I've got very interested in structures in recent years, mainly from an interest in railway history, but it must also have rubbed off on me from my son (who fancied a job with Arup being a structural engineer himself)
