How would you translate "Gleishalle", or "Geleisehalle"?

Hello Leander,

The term you are seeking is "train shed".

The direct translation of Gleishalle is rail hall.  From the pictures
of the main station in Frakfurt at
http://mitglied.lycos.de/Muehlheimer/Hauptbahnhof/Hauptbahnhof.html
you can see that the Gleishalle is the covered section of the station
where the passengers board the trains.

In my searches, I did come across the term "rail hall" in English, but
it appears only once or twice, which leads me to believe it was an
incorrect translation rather than an original term. Another term, that
appeared more frequently was "train shed".

In the "Building Types Thesaurus" produced by English Heritage, as
featured on the SINE (Structural Images of the North East) database at
the University of Newcastle-Upon-Tyne, I found the following
definition for this term:

TRAIN SHED
Definition: A canopy or building to cover the platforms in a railway
station.

You and Google answers are worht their weight in gold! The trouble is,
I don't have that much gold (or any at all, actually), but I should
like to guve you a small tip for a really marvellous answer! Thank

Hello Leander.  I'm glad to have been of assistance, and thank you
very much for the tip.  Of course, gold is nice, but those five shiny
sparkly stars also mean a lot to most of us researchers too!  :)
