Positive Train Control (PTC) is advanced technology designed to prevent train accidents by errors such as overspeed conditions or overrunning red signals
These systems will increase safety on our nation’s freight and commuter railroads.
What is PTC?
Three Components of PTC Systems
Wayside/Track Systems
Onboard Equipment
Office Servers
Wireless and ground-based
communication systems tie each
together
How Does it Work?
GPS satellites send information to trains and crew members on their
location and areas where trains should use caution.
What Happens Next?
Train receives information about route when leaving
station
Wifi communication systems and GPS send operator any changes on the route,
communicating with wayside equipment and servers
PTC tells onboard operator to slow and, if no response, system
automatically applies brakes
