It's apparently very successful in Japan and has increased productivity and safety significantly. But it hasn't caught on elsewhere around the world because workers seem to think it's...well, really silly, and feel foolish doing it.

In the MTA’s case, conductors point to a fixed black-and-white “zebra board” to confirm a stopped train is correctly located along the platform."
