Here's the solution.
1. At each train station, hire 2 kids who's graduated from cross walk patrol back in elementary. (these guys know they're stuff)
2. Have a reputable institution *insert any elementary school here* write up an exam on "How to cross roads safely."
3. Hirees need to pass this exam once a month in order to work these crosswalks at these c-train stations.
4. These kids will each be armed with a walkie talkie so they can tell the kids at the next c-train station when a train is on the way. They will also be armed with big red stop signs.
Don't worry guys, I've done the math. This is fail proof. Write your city officials to get this passed.
