Yellow Bump Strip and the Yellow (and sometimes orange) Line on Platform Edge

[Quill Depot]

Wondering when which one was implemented into the subway. Most stations have the Yellow Line, but all more used stations have a bump strip. I'd guess the yellow lines are a product of the IND but l don't know for sure.

It's not division specific. Originally, you only had the yellow painted wooden "rubbing board" at the very edge. Then, probably int he 80's, they decided to add yellow or orange strips (the latter, often textured like sand), to mark a limit of safe standing for customers. More recently, probably begininng in the 90's, especially with ADA awareness , they decided to add bumps, which would be more noticable by feel. These are either rubber strips, or even new ceramic tiles, when new platform tiles were added to some stations.

In some places, you even see the newer bumps, and the older strip together, and the edge is always yellow, new platforms get thick plastic ones that are thicker and bolted to the concrete underneath the edge.

I hate the feel of those damn things.  Sometimes the platforms are so narrow and or crowded that there is nowhere else to walk but on the platform edge.  I'm sure that's done on purpose to deter people from walking on the edge.

Still, the law is the law, and this is the standard now...

Think of it as a warning track and move on.

It's mostly so that the blind don't end up walking off the platform; otherwise, all of the platform would feel the same to them.

Whenever the platform is so narrow that I have to walk on the bumps, I always feel like slipping off the bumps and falling on the tracks.
