Trams can't go on highway=unclassified as far as I'm aware, unless  
there is a separate highway=tram tag or way.
In central London there are many roads that are all traffic one way  
and bicycle+bus+maybe taxi in the other direction, I'm thinking of  
splitting them into separate ways.

For island platforms I use a way for each platform with a ref, and  
then a footway at each end to link them, maybe not the best, but kinda  
works.
