Amtrak derailment focuses attention on railroad safety technologies

Positive train control, or PTC, seeks to create a complex infrastructure network for railroad lines which enable the real-time sharing of information between trains, rail wayside devices and software programs referred to as “back office” applications. The communication system tracks a train’s position and movement and determines any speed restrictions as well as the state of signal and switch devices along a railway. If a railway vehicle is speeding or a risk of a collision develops, the PTC system takes control of the train away from a human operator to reduce the speed or take other actions to prevent a collision.

Boeing Invents: The Pursuit of Safer Air Travel

A recent fire onboard a Boeing Dreamliner at London’s Heathrow Airport refocused concerns on the recently developed cruise liner, which was maligned with battery fire issues earlier this year. In early July, a high-profile Asiana Airlines crash in San Francisco involving a Boeing 777 airliner has also troubled the company, although the investigation seems to be focusing on pilot error in that case. Still, when dealing with air transit there is zero margin for error. When errors do occur when an airplane is in use they frequently are catastrophic, so the search for safer technologies is a never ending pursuit. Today in our Companies We Follow series, we’re taking another look at Boeing, especially taking a look at their efforts to develop even safer systems of airborne transportation. Some of the U.S. Patent & Trademark Office documents we feature here highlight Boeing’s improvements to emergency systems on aircraft.
