I am in HK now and today's riot/march/disturbance affected down the MTR Tsuen Wan line which was "red" earlier skipping Admiralty and Wan Chai stations completely (IIRC those two) but it is now green again. Airport Express was green all day and still is.
In Kowloon it was like nothing was going on, including the Tsuen Wan line as far as TST. Buses normal and very little traffic unlike a weekend where everyone is about.
I would not have wanted to be on the Island today just using common sense of avoiding a million people anywhere especially angry ones who are being shot at with tear gas and water. I've run from tear gas in Managua and that was enough for life.
