[OSM-talk] Bridges / viaducts for railways

Hello,

I'm a bit confused about these tags:

railway=viaduct
bridge=yes
cutting=yes
embankment=yes

I assume that 'viaduct' covers these sort of elevated rail lines so that
bridges are just for, well, bridges over other ways:

Why is it not a property like bridge, cutting etc. and will it render
correctly? Should it be changed to viaduct=yes?

The train lines around south London are pretty much always one of the
above and I'd like to get the tagging right.

Kind regards,
Tom
