HENRYVILLE, Ind. (WDRB) -- The mother of two children who died in a southern Indiana train crash is now charged with their deaths. 

Court documents show Ericka Fouch faces two felony counts of neglect of a dependent resulting in death, two felony counts of causing a death when operating a vehicle while under the influence of a controlled substance and driving with a suspended license. 

Adalynn Fouch, 5, and Wyatt Fouch, 4, were killed June 28, when the SUV they were riding in was hit by a train on State Road 160 in Henryville. Ericka Fouch, who was driving the SUV, suffered serious injuries and required surgery following the crash. 

Clark County Prosecutor Jeremy Mull said a blood sample drawn at the scene shows Ericka Fouch had nordiazepam, amphetamine, meth-amphetamine and THC or marijuana in her system. Court documents show she admitted to taking drugs an hour before the accident.

"When you are the parent of a child, you are responsible for the well-being of those children," Mull said. "And to use drugs and get behind the wheel and drive with those children in there, and then ultimately to kill them because of that, that demands accountability. It just does."

Mull said if convicted of all counts, Ericka Fouch could be sentenced to up to 42 years in prison.  

Josh Hamilton, who works at an auto repair shop along the train tracks, rushed to help the day of the crash. He recalled that horrible day. 

"The officers or somebody that day had asked if any drugs had been used, and she said like an hour prior to driving," Hamilton said. "And the sad thing was the kids. They were in car seats, but they weren't strapped in. And so when the train hit them, they just bounced around all over the car."

Investigators examined video from the CSX train, which shows the SUV driven by Ericka Fouch did not stop before it hit the train.  Video and audio show the train was blowing its horn, as it approached the flashing railroad intersection. 

There are no railroad crossing arms at the intersection where the train collision happened.  Neighbors said at the time of the crash that the crossing needs more than just lights to warn drivers when a train is approaching.
