The Mobile Mapping system and the Rail-SIT software implemented to verify the regulations compliance of the Emilia Romagna railways

news FER animated

On behalf of the Emilia Romagna Railways (Ferrovie Emilia Romagna), Siteco started a project to verify the railway clearance outlines, with respect to the EN 15273-3: 2013 European Standards.

For the railway inspection, Siteco used the Road-Scanner4 Mobile Mapping system associated with the Rail-SIT software application, expressly developed for optimizing the analysis and inspection activities typical of this sector. The combination of hardware and software allowed Siteco to provide the Regional Body with a complete solution.

The Mobile Mapping system, more and more successfully implemented and exploited in the railway sector, allowed the track detection in a short time, with minimum effort and an unthinkable efficiency compared with the use of traditional tools.

news FER 3Starting from the point clouds and the trajectories produced with the MMS, with Rail-SIT it was possible to process automatically the collected data,  extract the geometry of tracks and catenaries, dynamically generate the clearance outlines, and calculate the interferences.

The first phase of the  F.E.R. included three railroad lines: Bologna-Portomaggiore, Parma-Suzzara, Bologna-Vignola.

news FER 1From the Mobile Mapping survey, the main geometric measurements of the lines were obtained automatically (3D-axis trajectory) with identification of the key parameters (plane and altitude curvature radius, gauge and superelevation).

Rail-SIT then made it possible to automatically produce sections with the relating dimensions, cylindrical views, track plans, with the indication of the generated sections and curvature radius, besides reports of the interference analysis and the track geometry.

Lastly, a library of all the parametric clearances was developed according to the European Standards. The library consists of an Excel file in which the clearance dimensions are calculated as a function of speed, superelevation, and radius of curvature.

All the documents necessary to define the state of the infrastructure were produced according to the standards in force. The survey data obtained were also used for planning some restoration interventions and railways adaptation.

The new technology used will allow F.E.R. to guarantee the safety of railway lines and their compliance with the European regulations easily and with limited costs.

The application had already been adopted by the Japanese company NIPPON INSIEK Co., LTD. (former ASCO-DAITO) to provide services to the Japan Railways, similar to those supplied by Siteco to F.E.R.

These implementation examples confirm the growing interest for SITECO's technology of automatic analysis and inspection in the railway sector nationally and internationally, and the flexibility of Siteco's solution capable of complying with any regulation.
