It is not a railway specific thing. We generally don't tag different  
things onto the same objects. If a subway entrance and a post box  
happen to be in the same spot, we still use two nodes (correct me if  
I'm wrong here, I assume this is so but I might be mistaken). If a  
country border ends exactly where the river is, we will usually have  
two ways using the same nodes, one for the river, one for the border  
- both using the same nodes.

I think the main reason for this is easy separatability. If I want to  
draw the Karlsruhe tram network on its own, then I can just extract  
all railway=tram ways in the area and throw them into Osmarender. If  
people would tag their ways as railway=tram *and* highway=something  
at the same time, then It would be much more difficult to get a  
"clean" tram dataset.

I agree that editing ways using the same nodes in JOSM is a bit of a  
pain (middle mouse button, ctrl key) and that this needs to be  
improved. But I am quite sure that ways using the same nodes make  
sense in a lot of cases.

Bye
Frederik
