Here's an idea about what to do with all that red-light camera equipment that the state of Illinois may eliminate later this month.
Why not install the units at railroad crossings and take a picture of a train entering the crossing and then time how long the train blocks the intersection? If the intersection is blocked longer than allowed by state law, the red-light camera information can be used to send a ticket to the railroad company.

Imagine how much money the cities and villages can get for that and maybe, just maybe, the trains won't be so long at these crossings during morning and evening rush hours.
