Please don't mess up bus routes.

Bus stops must be added with role of "platform" IN THE EXACT STOPPING ORDER, and ways must be added in the exact order.

Also please make changes only after the reorganisation is effective.

There is no consensus whether the full or short form should be used for operator=* as mentioned on the wiki page. Therefore the most common name is typed into it.

osm principle: map what's on the ground. There is no ambiguity on the ground here. The ground is clear without any exceptions.

1. owner= in combination of route=railway is good (the railway is owned by KCR), but not on the service themselves (route=train or route=subway). The fact that MTR uses KCR trains on certain train services does not mean KCR owns the train service.
2. Maybe use dual_carriageway=yes or no.
3. The wiki page also says that highway=motorway_link means motorway restriction. In general the _link won't change mid-way however for motorways it's legally different before and after the sign. (For example, stopping restrictions aren't valid before the sign)

I'm also offended by you adding a lot of tags which are either wrong (such as owner=* on bus routes), both undocumented and meaningless (such as carriageway=*), or not following the universal wiki documentation (like the motorway_link limit).

1. The long-standing agreement is that highway=motorway is used "strictly in the legal sense", and highway=motorway_link has motorway restrictions. The wiki page clearly specifies that the link starts where the regulation commences and ends

"Besides its use for on/off ramps, motorway_link is also used for the slip roads/ramps into and out of motorway service areas/rest areas. In this case the motorway_link should go from the motorway towards the services as far as motorway regulations (for example no pedestrians) apply. In the UK, this is indicated by a sign. Similarly the exit road from the services should be a motorway_link from the point where motorway regulations commence.
"

2. carriageway=* is not documented anywhere and has no meaning here. access_control=* also the same.

this is a strict NO!!!!!!!!! not private, not permit, not any other values. The road sign is very clear - "no motor vehicles except taxi"

apart from this he has caused a lot of mess in other areas as well, most notably tagging slip roads outside the legal limit as motorway_link (which the consensus is that motorway = legal expressway and tunnels delimited by signs)

The tags I removed are clearly invalid. service and passenger tags are clearly invalid here as the routes are normal routes (maybe with the exception of 96R). They are general routes serving general passengers. Also owner (a bus route can't be owned) and brand (there is no brand for KMB & LW routes).

Also there is no PTv3. The new proposal does not create a PTv3. stop_position here is redundant and mostly unverifiable (especially in rural areas) so I'm gradually removing them when updating bus routes.

but this is clearly not residential - it is used for THROUGH traffic by buses and non motor vehicles.

I'm going to change it to tertiary as on King's Road - it's definitely not a service

highway=secondary

A highway which is not part of a major route, but nevertheless forming a link in the national route network. In developed countries it normally has 2 lanes and the traffic for both directions is usually separated by a central line on the road. In areas with worse infrastructure road quality may be far worse.

Des Voeux Road Central (both bounds) matches this description perfectly. It is not part of the trunk road network but it is an important link throughout the Central area. However in westbound this link is open for franchised buses only, and it is an very important link for buses going from Wan Chai to Sheung Wan.

This is from the wiki description of highway=service:

Generally for access to a building, service station, beach, campsite, industrial estate, business park, etc. This is also commonly used for access to parking, driveways, and alleys.

This is totally irrelevant for Des Voeux Road Central. And it is not used only because of certain class of vehicles are prohibited.

This road is so important because it is a major road traversing the city centre to the extent that only franchised buses are allowed to ensure smooth operation. When people sketches a road diagram of Central this is one of the first roads to mind. highway=service is totally inappropriate for use on such major roads. They are used for driveways, access slips, etc. which does not form part of the road network.

The fact that motor vehicle is not allowed has no relationship to the fact that the road is a major road inside the road network. No one in the right mind will think that Des Voeux Road Central in the city centre is a "service road".

A motorway link must connect to a motorway. This doesn't.

highway=motorway_link has implication that motorway law also applies in the area

the boundary of motorway_link is also limited to the ramp of the "expressway / tunnel area" signs

1. They are clearly not the same network according to the official usage. They are always listed out separately as MTR Bus, Light Rail, MTR, etc separately. Each of these are governed by different regulations. All these networks combined are called "綜合港鐵系統 Integrated MTR system".

Adding salt to the insult we may even consider the "Airport Express" in different network than the rest of MTR as well

1. The MTR Bus (港鐵巴士) routes are a separate network. They are not part of the MTR (港鐵). The MTR operates the following networks of routes:
- MTR
- Light Rail
- MTR Bus
- MTR Feeder Bus
- Ngong Ping 360
- High-speed rail
etc.

2. What do you mean by partially integrated? For example, if I use S1 as the example, and consider each franchise a network, it belongs to both LWB franchise network and CTB franchise 2 network. The "network" tag clearly can't cater for this situation.
