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.

See our current fleet below:

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

650-Series Testing Vehicles

The 650 Series provides track geometry and rail profile measurement data along with track strength information from our patented lightweight load axle in a medium duty package. This versatile testing vehicle has the flexibility you need to get a comprehensive assessment of your track condition to keep your track up and running safely and efficiently

Included with a TrackSTAR 650 series vehicle:

- Medium-duty Truck and Chassis (F-750 or equivalent) fully equipped withall gear necessary to perform on road and rail, as well as to host measurementequipment

- Custom rear walk-in compartment

- Exterior conspicuity lighting

- Interior and Exterior LED Lighting

- Access panels for easy deployment and inspection of Load Axle and ARGUS system

- Holland’s patented lightweight load axle technology

- ARGUSTM Track Geometry Measurement and Rail Profile Collection System, located at applied load, which includes:
Four railsensors
One System Unit (houses inertial components, customized circuitcard for signal processing and geometrycalculation)
Support structure and deploymentmechanism
Associated cabling

- Associated auxiliary equipment
In-cab displays for monitoring of systems
Inverter, power outlets and powermanagement
Tachometer & GPS
Computer rack
Work station
A/C unit
Storage for tools and equipment

- ARIES Operating Software
Geometry System operation, data review and editing, and load axlecontrol

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.
