I’m going to the “Lastic” now.

By loud communication, the mechanic calls the controller. and their dialogue.

M: Controller, go to the 9 wagon.

Q: What is there?

M: There, one of the passengers presses a button to open the pad. If he is a disabled person and needs help, help him.

If not, put it on your neck so that it doesn’t press.

...

People in the wagon roar.
