A Role for Smaller Suppliers?

The big suppliers aren't the only ones with something to offer the PTC arena. Numerous smaller, entrepreneurial players are now thinking in terms of technology that will fit nicely into a broader PTC context.

One example is Global Rail Systems of Marlin, Texas, which has developed a passing siding automation system called FAS-PAS ™. It's designed to allow a train crew or dispatcher to remotely control a power switch in dark territory. Two methods are available: time locking of the switch, normally deployed when it's being controlled from the locomotive via DTMF audible tone commands over voice radio, and approach locking, normally deployed when the dispatcher is controlling the switch via data radio. For both methods, FAS-PAS ™ provides field equipment for failsafe switch control and locking. With time locking, a voice message provides feedback to the train crew for advance switch point position indication. With approach locking, a wayside signal provides that information.

FAS-PAS ™ will interface with the vital switch point position indicators that are being incorporated into many PTC systems, through any type of communication method. It's "PTC ready," says Vice President-Sales and Marketing Ron Martin.
