Great stuff (and great minds!). Is there an agreed (or common)  
approach to tagging abandoned/dismantled railway stations? There isn't  
anything in map features about it, but it would be great content to  
have in there in OSM, particularly for those with an interest in  
historical railways. To render historical stations on these maps would  
encourage contributors (as in 'render and they will come').

What about proposed lines and stations? There are a number of these in  
the UK and again it would be very useful to be able to see where they  
were. railway=construction construction=rail? railway=proposed  
proposed=rail?

On the subject of historical railways, can one use start-date and end- 
date attributes to animate the life of the UK's railway network,  
watching it growing a shrinking over the years. There may be some  
complex cases where a line opened, closed and was then re-opened, but  
we could leave that for now in order to get the basic information in.

Could these maps render the 'lanes' tag, around which there seems to  
be an emerging consensus  for showing the number of tracks, typically  
1 for single track working, 2 and the 4. The rendering should use a  
different style for single track working and multi-track, typically  
using a different symbol.

How about rendering speed limits using colour? There are some sections  
of track with max-speed already, but this rendering would greatly  
encouraged if it for other areas.
