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

[Tony Shield]

Guys

Recently changed Chorley station adding more details. Added covered=yes 
cos there is a canopy for us to huddle under but not the whole length of 
the platform, there are also bus shelter type of shelters so shelter=yes 
was also added.

Checked that my changes had rendered ok but found to my horror that the 
platforms had disappeared. Investigations showed -

  * Hiding railway=platform with location=underground, tunnels and
    covered=yes

Have changed Chorley to delete covered tag - expect the render to show 
as expected for the surface.
A quick overpass  (inexpertly done) shows the following railway stations 
may be affected adversely -
Holyhead
Manchester Airport
Salford Quays - Anchorage
Manchester Piccadilly
Harrogate
Hull
Sleaford
Bury St Edmunds
Guildford
Bracknell
Westbury
and many in London and there are others

I know we shouldn't map to the render but the meaning of covered seems 
to vary globally.   I know that
Manchester Airport
Salford Quays - Anchorage
Manchester Piccadilly
Harrogate
Guildford
Bracknell
Westbury
are all similar to Chorley - I've visited or passed through them; 
Manchester Piccadilly  I know well and the solitary (covered=yes) 
platform 12 is the same as the other 11 platforms - mostly under the 
glass train shed.
In my mind accurate representation of platform location is so important 
when travelling.

At the end of this week (2nd June) I intend to change the platforms I 
know to remove covered=yes, if you disagree please challenge.

Looking at Manchester Piccadilly I can see that there are many 
opportunities to improve the data and thus the representation, anyone 
fancy a mapping party there?
