I remember a photo in Model Railroader once of a bridge which was really only a
single track bridge had two tracks crossing it, the 2nd track was interleaved
with the first, something like this horrible ASCII drawing:

Another factor to consider in track spacing is how easy it is to get the 2nd
track to be at that spacing if you want it connected to the 1st track somewhere
in the layout.
