Track and Train Studies

Improve Performance and Reliability with our Track and Train Studies

TÜV Rheinland train performance studies provide valuable insights into railway efficiency and performance. Having worked with some of the biggest train and rail companies in the world, the TÜV Rheinland team has unrivaled experience in evaluating and assessing train handling, fuel consumption, train make-up instructions, wheel profiling, signal spacing and more. Track inspections and rail grinding are other aspects of TÜV Rheinland's train performance studies, making sure your track and trains are running safely, smoothly, and efficiently.

Our Services for Track and Train Studies

Rail Grinding Consultation

Rail Grinding is a beneficial practice that allows the railroad to control the integrity of the rail surface by periodically re-contouring the rail surface with a rail grinder. Increasing wheel loads in the rail industry have a tendency to subject rail to excessive fatigue which can result in the deterioration and shelling of the running surfaces. Shelling on the rail gage corner can lead to fractures in the rail head and increase the potential for catastrophic failure of the rail under load.

Due to the potential impact of the re-contoured rail head, any grinding program should be closely monitored and controlled. Excessive, inadequate and/or imprecise grinding can lead to a sub-optimal wheel/rail interface and accelerated wear rates.

Track Inspections

TÜV Rheinland has a team of inspectors available to inspect yard tracks, terminals, sidings and main lines. Our inspectors can:

  • Review track conditions
  • Make and prioritize recommendations for repairs
  • Develop long-term maintenance schedules
  • TÜV Rheinland's Track Inspections can be used to classify track according to FRA standards. Rail Sciences can also make recommendations for upgrading track class.

During the course of a track inspection, TÜV Rheinland's inspectors review the condition of the Rail, Switches, Frogs, Crossings, Ties, Ballast, Drainage, Surfacing Gage, Crosslevel, Fasteners, and Joint Work

Fuel Consumption Studies

Fuel is a large expense for the railroad industry. TÜV Rheinland can help reduce fuel costs by helping railroads identify factors, through the application of scientific analysis, that affect their fuel consumption costs and help railroads make informed decisions. Factors that influence fuel consumption can be categorized into three groups: Equipment Type, Operating Procedures and Track and Terrain.

Signal Spacing Studies

  • Evolution of Signal Spacing
  • Traditional Signal Spacing Calculations
  • TÜV Rheinland's approach to Signal Spacing Calculations

Wheel/Rail Profiling

An optimized wheel/rail interface provides numerous benefits to railroads and car owners

  • TÜV Rheinland has been active in helping railroads optimize both the shape of the rail and the shape of the wheel for various railroad applications. TÜV Rheinland uses the most modern technology available, the Beena Vision LazerView profiling system, to measure and quantify the shape of the wheel. TÜV Rheinland collects and analyzes wheel/rail profile data under various operating scenarios. TÜV Rheinland uses this information to provide clients with the optimum shape of the wheel and/or the rail for different operating situations.

Train Handling Studies

TÜV Rheinland has extensive experience using computer simulations to analyze train handling for numerous railroads. Our train handling analyses help the operating departments of railroads to:

  • Minimize in-train forces
  • Maximize train speeds consistent with safety
  • Evaluate both dynamic and air brake operations
  • Develop tables recommending the minimum number of dynamic brake axles

Train Make-Up Studies

Train make-up rules dictate the tonnage distribution in trains. The tonnage distribution, in turn, directly affects the in-train forces that are developed as the train moves over the road. Excessive in-train forces can lead to unsafe operations and derailments. Proper train make-up is critical for efficient railroad operation and safety. TÜV Rheinland has performed computer simulated train make-up analyses for nearly all the major rail carriers in North America. These studies usually involve hundreds of simulations using several train consists, various train handling techniques and various draft gear systems. Many of the studies involved specific territories using actual track grades and curvature. TÜV Rheinland has also performed several intermodal train make-up studies evaluating the instructions for two connecting interchange carriers for consistency.
