Contract Testing

Holland's contract testing vehicles (TrackSTAR®) will simultaneously collect track geometry, track strength, and rail profile measurement data to provide a comprehensive assessment of your track condition, primarily from a safety perspective, but also to help direct you to the most effective use of your maintenance and capital funds. Our TrackSTAR® vehicles allow us the flexibility to provide testing services to Class 1, regional, short line, transit and industrial railroads throughout North America. An experienced two-person team, fully trained in on-track safety, operates each testing vehicle. With testing speeds of up to 35 mph, our vehicles can test over 100 miles of track in one day. We provide everything from one-day testing services to multi-year term programs and can customize programs and solutions to fit your needs.

400-Series Testing Vehicles

The Holland 400-series GRMS TrackSTAR units are the largest of the fleet. The load axle on these vehicles can apply up to 15,000-pound vertical and 10,000-pound lateral loads to the track, generating L/V ratios between 0.5 and 1.25, depending on the actual applied loads. Loadings such as these, which replicate the type of loading that poorly performing vehicles are likely to generate, provide a truer picture of what the track actually “sees” under traffic.

Data from these GRMS systems can identify:
• Loose, missing or broken spikes or elastic fasteners
• Worn, missing or broken tie plates, pads or shoulders
• Clusters of weak (decayed, deteriorated, abraded, spike-killed, plate-cut) or missing ties
• Differential plate cutting
• Loose bolts or worn joint bars
• Gage widening in timber-tie track
• The delta between static and dynamically loaded conditions
• Areas with poor track-gauge strength
• Areas of track that are susceptible to excess cant due to rail rotation
• Indications of rail seat deterioration in concrete-tie track
• Areas that pose potential derailment risk

800-Series Testing Vehicles

The 800-series TrackSTAR units are designed to collect geometry on mainline, branch line and yard tracks. They provide the full suite of geometry measurements and identify exceptions and / or deviations in track geometry. This series incorporates half profile measurement, which enables the system to characterize rail type, gauge, gauge-face wear, rail cant, gauge-face angle and other rail-related parameters.

850-Series Testing Vehicles

The 850-series TrackSTAR units provide all the capabilities of the Argus system used on the 800-series vehicles, with the added benefit of a GRMS-type mini load axle that applies up to a 3,000-pound lateral load, which is sufficient to find broken spikes and missing or broken fasteners that may not be identified by unloaded geometry cars or visual inspection.
