Pardon me, but I'm not sure about the purpose of this "trolley".

Do they have any significant tourism industry over there? Cause tourists would find it cute and picturesque, maybe like in New Orleans or San Francisco, but how actually convenient would it be to locals?

For example, what about the disabled in wheelchairs or young parents with their cumbersome baby strollers? You often see moms who have to use elevators here, while you run up or down the stairs, and when trains and platforms are not at grade, you often have to help them to be a gentleman, so you don't look like a rude scornful asshole...

Modern public transportation must be accessible and comfortable to anyone. Not to mention, clean too.

I sure hope their thing is successful enough (they'd better grow tourism), but I certainly won't recommend the same where I am.
