Inertial Track Geometry Trolley: iTEC

Inertial Track Geometry Trolley: iTEC

The trolley measures track geometry and records results of track condition visual inspections. Irregularities in two planes (horizontal and vertical versines) in relation to both rails are measured using an innovative inert system consisting of cutting-edge semiconductor gyroscopes and accelerometers. A new method for measuring horizontal and vertical irregularities enables the obtainment of highly repeatable measurement results. Calculated values correspond to measurements performed using a wire versine meter or measurements made by state-of-the-art measurement cars. 

The trolley is easy to use and has a modular design enabling its transport by one person and fixing on a track in less than 5 minutes. In addition, the possibility of using the trolley on any track gauge significantly increases work productivity. 

Track geometry measurement results such as values of width, cant, horizontal and vertical irregularities, covered distances and GPS positions are recorded in the device memory on a real-time basis. The trolley can be easily and quickly (ca. 26 kg in weight) removed from a track to allow the safe passage of trains. Measurements can be instantly resumed without calibration or zeroing.

The TEC trolley meets the requirements of the EN 13848-4 standard. Measurement results generated by the trolley are consistent with the requirements of the Polish Railway Lines (PKP PLK).


The trolley control panel can be removed, facilitating the overview of results after the completion of measurements. The transfer of data to a PC is performed via a USB Pendrive. The trolley is supplied with the GeoTEC System software (for PCs) enabling, among other things, the graphic presentation and comparison of measurement results as well as the printing of measurement reports or calculating typical track quality factors. Measurement results are also available in the tabular form containing track defect locations. Measurement data can be exported in MS Word, MS Excel and PDF formats.
