The TSC trolley measures track geometry. The measurement
results include values of track gauge, cant, horizontal and vertical irregularities along with the calculated gradient and twist parameters.

track geometry database systems: Geo-TEC
The database makes it possible to store and process track condition data collected using track gauges. Measurement data are localised according to the actual railway network model developed for the organisation.
The GeoTEC database makes it possible to process information about the track condition collected using the electronic track gauges.The system consists of two subsystems: database with a model of the railway network model, and the database with the measurement results. Measurement results are localised using the railway network model used, relevant to the actual structure of the particular organisation.
Each user develops this model during implementation of the system, defining it according to his railway network area, specifying areas, lines, and other objects. The GeoTEC package makes it possible to obtain the diagnostic assessments for the selected line sections, and the cumulative synthetic reports, similar to those obtained from geometry cars, and also provides functions for following the track geometry changes during its operation.

GeoTEC makes assessment of track condition possible, basing on the synthetic quality coefficients, and the software features can be easily adapted to requirements of its particular users. An important feature of this database is its capability of storing the real track geometry measurement results along with its design specification, so comparison of the actual track geometry and the theoretical one is possible.
Moreover, it is possible to compare many - historical - readings of the track, to detect the rate of its deterioration in terms of particular parameters and/or the track synthetic quality coefficients. All measurement results acquired using trolleys and track recording cars are pre-processed, inclu-ding their alignment, before storing in the database, so that diagnostic analyses do not require the user to look for any specific readings. Using the optional module the user can access information sto-red in the external turnout measurement and diagnostic database, not included in GeoTEC product.
