Alright, I get that they blocked the doors with the railing, but why do you need it on both sides? Also, why is it placed again on the inner side?

This surely looks modern. But how am I supposed to reach the escalator?

I've played enough games in my life to know there is a hidden trap door here.

Those 3 steps are surely helpful to get up to the railing. Nothing is better than a well accessed railing!

Let's break the law right here right now. I'm sliding down this railing.
