Please stand behind the "red" line..

There is something new today.

Some of the MRT stations have changed the yellow line to red line. I guess the announcement will be changed to "please stand behind the red line..." :p not sure if the red line will be applied for all MRT stations.

Why is that so? does it means to "make" someone follows the rule, it has to be "forced" ? it does not come "automatically" from themself? or to make people understand, it has to be a "strong color" , red color = does not allow?

This gives me an idea: to make other people notice our existency, probably we need to wear a red-color clothes??

Reserved seat ?

Everyday, I am using public transport - MRT , so any new thing will be easily notice.
Today there is a new sign for the seat that was written as "Priority Seat" now changed to "Reserved Seat".
It should have some reason why from Priority seat changed to Reserved seat (with bigger sign). Does it mean no more "courtesy", "considerate" or "kindness" in this place? sad if that really happens.
We will see if someone who is sitting on that seat will give up the seat for somebody else who need it? or does it mean no one allow to sit except persons who are on the sign board list?

Whatever reason behind this, should not be necessary to change the signboard if each person has a good personality and respect to others.
