I think it makes sense. Vast majority of people either don't want to, are aren't able to walk up those high steps. It's stupid to have a long line on the right to cater for a couple of folks who couldn't wake up on time.
Most of the people who walk up the left do so purely to obey social convention.
Hey, if you want to walk upwards, they have these things called stairs, with almost no people using them, so enjoy yourself.
It is still faster walking up / down the escalators. Quarry bay is like 42m down and going from exit C down to purple line is like 500m of walking. When one of the 3 escalators are broken, walking up/down stairs is quite an effort, plus the stairs are like around the side of where you need to get to.
It's like standing on both sides of the travelators in HK Airport, or Hong Kong station to Central. It's a 15 minute from terminals to immigration. You could assert our rights and block both sides, but some people want to walk on the travelator to move a bit faster.
It's not like a travelator though. Travelators are designed to walk on. That's why they go slower than normal walking speed to encourage people to walk. You are not at risk of serious injury if you fall. Escalators are not designed to walk on. I don't know why they have extra high steps and sharp edges but you're basically f***ed if you fall down one. They also travel faster, or at the same average speed as walking up stairs. So it's not a good comparison at all.
There's also no point discussing individual stations. Some will be more difficult, some will be easier.
The world isn't designed on what works for you. It's what works for most, or at least should be.
I agree that it's polite to leave space and stand on the right in non rush hour times. But when it's busy enough where you have to queue up to get on the escalator then people ought to stand on both sides, which is usually the case anyway, before this initiative.
The escalator is literally - in many non-english languages - called "moving stair".
Also the English definition of escalator:
"a moving staircase consisting of an endlessly circulating belt of steps driven by a motor, which conveys people between the floors of a public building".
So yes, it is a stair.
Toshiko Nitta, a professor emeritus at Bunkyo Gakuin University in Tokyo and an expert on escalator safety, advises those in a hurry to use the stairs instead. “Leaving one side open isn't necessary. For both safety and efficiency, it's crucial for passengers to stand on both sides," she says.
