Please stop retagging trunk roads as highway=motorway. If a road doesn't have the green highway signs then it should be tagged as highway=trunk (or highway=trunk_link for ramps/slip roads and Penny's Bay Highway), and if it doesn't have a route number then it should be tagged as highway=primary (except Sha Lek Road and Penny's Bay Highway).

Why did you delete these?

The Airport Express is separate from the rest of the MTR system in fare system and high speed, and is therefore tagged as a main line (railway=rail). The Tung Chung Line tracks, on the other hand, are tagged as a metro line (railway=subway).

Only the parts which are marked by signage as tunnel areas should be tagged as highway=motorway.

This road is not even part of the route system (i.e. routes 1–5 and 7–10) and should not be tagged as a motorway.

Like Prince Edward Road East, even if a road is constructed similarly to a highway, it should not be tagged as "highway=motorway" unless it is part of the route system and has green signage (except for Sha Lek Road).

Like Prince Edward Road East, even if a road is constructed similarly to a highway, it should not be tagged as "highway=motorway" unless it is part of the route system and has green signage (except for Sha Lek Road).

Like Prince Edward Road East, even if a road is constructed similarly to a highway, it should not be tagged as "highway=motorway" unless it is part of the route system and has green signage (except for Sha Lek Road). Airport Road is not part of Route 8 and does not have green expressway signage.

Like Prince Edward Road East, even if a road is constructed similarly to a highway, it should not be tagged as "highway=motorway" unless it is part of the route system and has green signage (except for Sha Lek Road). Ma On Shan Road is not part of Route 2 and should therefore be tagged as a primary road (highway=primary).

The East Rail Line is, like the West Rail Line, a metro line (railway=subway). The Intercity services, on the other hand, are main line trains (railway=rail). Since the spur line is not served by main line trains it is tagged as railway=subway.

Ching Cheung Road, while part of Route 7, is not classified as an expressway/motorway (highway=motorway) and should be tagged as a trunk road (highway=trunk), like Princess Margaret Road.

(Tunnels and tunnel areas are also tagged as highway=motorway.)

There is a difference. Tag roads with highway=motorway and highway=motorway_link only where the highway signs are green.
兩個（highway=motorway和highway=trunk）不是一樣的。只用highway=motorway和highway=motorway_link如果路上的路標是綠色。

Stop it. 停止。
You're not helping by continually changing highway=trunk to highway=motorway. That's not how it works.
highway=motorway
highway=trunk

Your changes to this map can be seen by everyone. Don't add things that definitely don't exist.

The previous tagging was correct. In future can you please only do large-scale tag changes like these with community consensus? Thank you

I notice you tagged the Airport Express tracks as service=siding... They're actually the fast line tracks. Will fix now

Aren't government maps copyrighted?

The Sheung Wan part of Des Voeux Road Central needs to be fixed up (preferably with a graphical editor) since the placement is quite off.
