ENSCO’s Point Asset Inspection System (PAIS) is a combination of multiple inspection systems tailored specifically for inspecting special trackwork assets such as turnouts (switch & crossing), diamonds, road crossings (level crossings), and derails.
The PAIS combines the following inspection systems together to provide a comprehensive inspection system
- Rail Profile Measurement System (RPMS) — ENSCO’s standard RPMS tailored for use with the PAIS where additional laser profiling capability is added and higher sampling rates are used to gain detailed measurements of components such as frogs and switch points. Additionally, the RPMS provides key measurements of the guard rail.
- Track Component Imaging System (TCIS) — ENSCO’s TCIS is used to obtain detailed machine vision images of turnout components such as tie bearers (sleepers), fasteners, and tie rods.
- Joint Bar Imaging System (JBIS) — ENSCO’s JBIS captures detailed images of turnout components such as switch point blades, heel blocks, frogs and guard rails.
- Additional Inspection Systems — ENSCO’s unique ability to synchronize all inspection data allows for additional systems such as the Track Geometry Measurement System (TGMS) and Ride Quality Measurement System (RQMS) to be included with the above detailed inspection data at point assets.
ENSCO’s PAIS utilizes data from all the above systems to capture data at the designated point asset locations and provide an organized data set for automated algorithms and detailed inspector reviews in the office using Virtual Track Walk® (VTW).
