Well, progress has been slow on this one, it's quite a complicated job and one that has not been helped by the fact that you really have to get the thickness of the steps right otherwise it don't fit together - It's 3.5mm or nothing in O gauge.

I've also built them with 18mm off the back faces so that I can make the overbridge in half relief. The sidescene will be mirrored to provide the illusion of the other half and the station beyond!

EDIT:

And here it is in all it's glory. The span is not glued on yet, I'll do this once the steps are fitted to the platform
