It shows the name and destination of the next three trains, and the stations that the next train stops at. Not sure why we don't have these in the US.
The LIRR (Long Island Rail Road) does; it shows the final destination at top and all the stops along the way underneath. If the sign only has one line, it scrolls to show all the stops. Most trains even have a sign in the car that shows what the destination and next stop are.
I'll take some pictures tomorrow when I pass through it.

There's a few (or, at least one) other picture, but thats on my phone (non-smartphone, so its a big of a dance to get pictures off of it).
