[Talk-GB] Railway Platforms - Covered=yes are not shown in latest rendering

[Dave F]

I think Carto & anyone who added it to underground metro stations have 
misinterpreted the 'covered' tag.

As it's not the whole length of the platform, you could add a 
building=roof polygon.

Shelters, bins, benches etc are better mapped as individual nodes at 
their locations, rather than adding them as sub-tags to the platform.

Cheers
