SUBJECT: Evaluation
KEYWORDS: Alarm Performance Test, FAST, HAL
ABSTRACT: Alarm performance tests of a ballast movement detector manufactured by Picton Technologies were performed by Transportation Technology Center, Inc. Tests were carried out at the Federal Railroad Administration's (FRA) Transportation Technology Center (TTC), Pueblo, Colorado, under the Facility for Accelerated Service Testing/Heavy Axle Load Program (FAST/HAL). The detector tested worked as expected. Separation of the weight at the bottom of the detector; the deployment of the visual alarm plunger; and the arming mechanism appeared free and unobstructed. By sound, the limit switch is activated as expected at about 4-inch extension of the visual alarm plunger.
