The suburban New York rail crossing where six people died in a collision between a commuter train and an SUV had undergone a number of safety upgrades in recent years, but some planned work was never done.

Records obtained by The Associated Press show that in 2009, state officials set aside money to install a third set of flashing warning lights at the crossing. For reasons officials can’t seem to explain, they were never put in.

It’s unclear whether more lights would have prevented Tuesday’s crash.

The wreck involved a motorist who stopped her SUV in the crossing.
