I work in the Texas Medical Center (the train goes right through it). The rail track goes over the turn lanes! So here you are thinking your clear and going to turn left and BAM! here comes a speeding train.

Just this week I notice they've embedded a series of red lights that delineate the turn lanes. The lights start flashing when the train is coming to show drivers that they shouldn't get in the turn lane.

They only built this rail line in a failed attempt to get the Olympics in Houston. (It goes from Downtown to the Astrodome/Reliant Stadium complex.)
