A 2012 Volkswagen Beetle appeared to have been traveling northbound on Sands Road when it attempted to cross the railroad tracks.

The Volkswagen was struck in a T-bone style collision by a ballast regulator that was being operated westbound along the train tracks.

A ballast regulator is a piece of railway maintenance equipment that is used to align and distribute stone or gravel, which supports railway ties, along the tracks.

Gillis said the machine belongs to Union Pacific Railroad, which was in the area performing a track tie replacement project along with other machinery.

The driver of the Volkswagen, an adult female, was transported by ambulance to the helipad at Mercyhealth Hospital in Crystal Lake.

A LifeNet medical helicopter responded and landed at the hospital’s helipad.

The extent of the woman’s injuries was unknown but officers at the scene reported she suffered a head injury.
