Few out there are not tired of my sign posts, but still he persists!
This was on the door of the train. I’m a little unclear about the third one.
Many of these towns have hills but Portugalete decided to add outdoor moving sidewalks to help. They also have a sign and again not all are completely clear. Not being able to take a baby carriage seems bad. I would think that would be a common use.
The third sign with the seated passenger x’d out is indeed perplexing. Is it a sign of bad manners to sit if others are standing? If so, what old people do? Flip off the sign?
Upon reflection I think I figured it out. In the area by the doors there are several fold-down seats. So they are saying not to use them if the area if crowded with people.
