Well, I have a story to tell here. Bare with me on this.
So, last week, I was on my home, heading uptown. It was at 86th Street. As usual, an R62A 
train arrived in the station at a fast speed. Nothing out of the ordinary. But then, at the last 3 cars in the back, it assigned as the 
train between Dyre Avenue the Bronx and Fltabush Avenue Brooklyn. When I enter the last car, it gets much worse from there. You can easily access the cab (don't worry though on this part; it was only half of the cab. The train controls were not accessible). Adding to that, the door to the rollsign was also open as well. I didn't enter the cab. I get of at 137th Street, I was shocked at what I saw.
Now, I must note this: I did not do any kind of stupid rollsign shenanigans or anything like what the Conquestors did. I just simply came across it. The only reason why I wanted to post this story because of because something was not right here.
Now explain me why that happened.
