Hi mike
It isn't normal for track to have sleepers (as per main line tracks) on metal bridges though there are of course exceptions.
On most metal bridges the track is supported on Wheel Timbers. These are longitudinal timbers of huge cross section and normally run the full length of the bridge. The tracks chairs are screwed down onto the top of these and metal tie bars and some wooded cross beams are used to hold the wheel timbers in place to prevent the track going wide or narrow to gauge. Some bridge have a metal decking onto which the wheel timbers are laid and bolted down to. While others (usually very small bridges) use a wooden decking. Brick built bridges normally have conventional ballasted track on them.
I'll try and locate some photos of the wheel timbers in use on BR and upload them.

Hi trainman
QUOTE On what is known as Chain Bridge in March, Cambridgeshire and part of the planned Wisbech & March Bramley Line, there are sleepers between the rails and across the iron bridge. If you care to go to www.freewebs.com/bramleylinesupporters and then their photo album, there is a photo of this same bridge and showing sleepers across it
Strange this one... The Bramley site takes a while to load then when you select Bramley Line Album it tells you to click on a redirect link to Photopic. When that loads all I can view is three sheets for text. No photos! I've left it for ten or so minutes but it wont upload any photos. I can only see some small pictures in the PDF contact strip! Does anyone else have a similar problem at this site??

Bramley pictures or should be?
