*snip* i dunno if you guys know what those are *snip*
They look to be train length posts.
We have something similar in Scotland/UK, they are to tell the driver where to stop on the platform. That way all the doors are at the platform and not away from the station.
The image above shows an example of what we have in the UK
They might not be, but it seems to be the most plausible idea.
