US Railways Introduces Train Speed ​​Control System

On the section of the railway between New York and Philadelphia, for the first time in the United States, a safe train control system - PTS (Positive Train Control) was installed.

It was here in the vicinity of the Frankford Junction that a major accident occurred in May. Then, at a speed of 170 km / h with a permissible 128 km / h, the passenger train, not fitting into the turn, went off the rails. As a result, 8 people died and more than 200 were injured.

According to a member of the National Transportation Safety Board (NTSB) Robert Sumvolt, if the RTS system had been installed then, the disaster would not have happened.

RTS is a programmable system that uses special track repeaters connected to computers on locomotives. When the train passes the transporter, the onboard radio switches to the desired channel to receive up-to-date information on speed limits and traffic conditions.

The system sends a warning to the driver when the train accelerates and starts braking if the driver does not respond. RTS also suggests stopping the train if an erroneous acceleration occurs, which could lead to a collision with another train. Recently, the equipment has been supplemented with an information storage system that can be used by investigators in the event of an accident.

The spokesman for the US National Railroad Passenger Association - Amtrak, Mr. Stadtler added:

“If the train with RTS stopped for some reason, we receive a notification. Video cameras are also installed inside, which gives us the opportunity to see the reason for the stop. "
