Modern systems of traffic control as applied to the Seaboard Air line Railroad company

ON december 6, 1941, the Seaboard Air Line Railroad placed in service the first segment of a major installation of a system of traffic control on its line. The segment was only 33 miles in length but it made history. It was a portion of a 65-mile segment of railroad to be electrically controlled from a remote location 157 miles from the most distant point. At that time this line became the longest control line for this type of service in the world. The system proved to be very efficient and economical, and expansion of the system was made as rapidly as material and labor could be obtained. As of today, trains operate the entire distance between Richmond and Miami - Tampa by signal indication controlled by modern systems of traffic control.
