RALEIGH -- Sunday's deadly Amtrak crash in Cayce, South Carolina may have happened more than 200 miles away from Raleigh's Union Station, but it still hit home for some commutors. 

"It puts you on edge a little bit about safety," said Tom Hubble, who was traveling by train from Raleigh to Pfeiffer University in Stanly County. "What if there is a problem? A technology problem or something like that, something with the tracks."

The crash in Cayce killed two Amtrak employees and injured more than a hundred people, including some North Carolina residents.

Service was back to normal in Raleigh on Monday, with even the affected route between New York and Miami making its scheduled stop at the station.

The North Carolina Department of Transportation says they are doing what they can to keep the state's roads safe. In particular, they say they are working to implement Positive Train Control (PTC), a computer system designed to stop trains from colliding. Congress is requiring commuter rail to install PTC by 2020 at the very latest.

"We currently own 8 locomotives and 5 cab control units and we're well on our way to equipping all of that state owned equipment with positive train control," said Allen Paul with NCDOT.

In the meantime, some riders still remain spooked by the South Carolina crash.

"It’s making me think more about if I should use Amtrak in the future or if I should take other modes of transportation,” said Hubble.
