Please don't blindly add suggested tag. The airport APM is not Light Rail.

`bus_bay=left` is the correct tag. It is not a bus lane, nor a bike lane. Don't count it in `lanes=` either. `cycleway:left=share_busway` is not correct here, or anywhere in HK.

How do you know if this section is under reconstruction or not?
Would appreciate if you use more descriptive comments.

Please don't randomly connect and draw.

Yes, I'm going to fix it now.

Hey, please don't delete the originals if they are temporary.

Please stop your damaging deletes. There have been complaints about your wrong "fix".

It's technically not wrong for the `building:part=` above.

Hi, that one is created as a placeholder for the PTI.

Or maybe not.

Long Ho Rd seems to be connected.

Please don't arbitrarily merge segments. They are split between the island and unseparated section. There is also `placement=transition`.

Please don't remove `ele=`

Please discuss at note/3146813

`leisure=track` should be used for ones forming a circuit inside parks, not `=cycleway`.

How do stations affect the line?

I have been adding `train=yes` to them, as I was told there was a compromise to make East Rail Line and Tuen Ma Line as `route=subway` on `railway=rail`. I must have accidentally removed some `subway=yes`. However they are in reality mainline trains upgraded as rapid transit. I have been contemplating to change them to `route=train` altogether.

1. `bus=designated` is only used on bus lanes, not bus stops.
2. `bus=yes` or this means all bus vehicles can use them, including non-franchised and private buses.

`vehicle=bus` is not valid. Please fix your application to accept `bus=`.

What are you trying to do again? You removed the English name, and made it non-lit. Please fix the application you are using.
