Curved sidings near turntable?

Rob:
Check for old photos of CN's Spadina roundhouse. They certainly crammed everything in there -- a reverse loop around the back wall of the roundhouse and a coach yard in the V at the front.

Thx, David. I'm also looking for some British pics as well since this is to be an S&DJR- or GWR-based layout.
