Examples of track measurement results obtained with the TEC trolley

Software for the PC platform, supplied with the track gauge makes it possible, among others, calculation of the track gauge gradient, track twist, and recalculation of the measured vertical and horizontal irregularities to 10 m long chords. Tabular printout of the measurement results is possible, with marking the mileage values where faults observed by the operator occurred, printout of the measurement results as plots, and also calculation of the synthetic indices according to regulations of the Polish State Railways, Hungarian State Railways or Dutch Railways - for evaluation of the track geometry quality - see figs 3÷5. The main advantage of the TEC track gauge system is its capability for evaluation and visualization the measurement results in a way similar to the one employed by geometry vehicles.

The track gauge user can select parameters, at his discretion, which plots should appear on the same page (max four plots). The plot demonstrating occurrences of events (e.g., switch, semaphore, bridge, etc.) and track defects (e.g., missing bolts, flash, skewed sleepers. etc.) is very important, as it is a precondition for the rational interpretation of the measured track geometrical parameters.

Example:

An example is shown below of the track geometry measurement made with the TEC track gauge. Assessment of the track quality has been done according to the Polish State Railways (PKP) regulations for the line speed of 120 km/h. The complete set of the measurement results' documentation consists of:
