More infrastructure objects?

[Matthias84]

If we take a look on www.openinframap.org there are a lot of intersting generic objects which might be rendered as well

Power

• mast
• substations
• solar panels
• wind turbines
• cabinets (even if not tagged dedicated to power)

Communication

• mast
• antenna
• towers

Traffic

• rails (with junctions etc. see OpenRailWayMap
• rail electrification (trains and trams)
• piers
• fairy ports / terminals
• tunnels
• bridges
• streetlamps
• traffic lights

misc

• manholes
• pipelines (including bridges or tunnels)
• cranes

There is Tordanik of osm2world which has a lot of experience in tags and 3D object placement. Maybe it's worth to get in touch?
