Portable Track Loading Fixture (PTLF)
ENSCO’s manually operated Portable Track Loading Fixture (PTLF) is the industry’s go-to method for spot-checking gage (gauge) strength. The PTLF is compliant with the American Railway Engineering Maintenance-of-way Association (AREMA) and Federal Railroad Administration (FRA) standards for gage strength.
PTLF – Portable, easy-to-use lateral strength testing for railroad crossties and fastening systems
Using the PTLF helps to identify locations of high derailment risk caused by gage widening conditions caused by weakened ties (sleepers) or broken or missing fasteners.
Track Inspectors can use the PTLF to spot check locations of concern, or check gage under load after measuring with a hi-rail mounted Track Geometry Measurement System (TGMS).
The PTLF brings a complete gage strength assessment to a railway when combined with a Deployable Gage Restraint Measurement System (DGRMS) which performs similar measurements, but at high speed from a rail bound vehicle.
The PTLF is based on research sponsored by the FRA and ENSCO internal research and development.
