The Mexico-Toluca interurban train


How can a map viewer significantly help the management of a transport line?

Since 1842, when operators were substituted for traffic lights in the Croydon train (England), railway signalling systems had advanced very fast.  Technology had adapted and improved the way that railways are being managed, focusing on security, shorter travel times and resources optimization.

The Mexico-Toluca interurban train will transport 230 thousand passengers per day. This 58 km journey will take 40 minutes versus the 2.5 hours that it takes to do the same journey bus. This ease access to the job and free time options between the two cities. It will reduce pollution and approximately 400 traffic accidents per year. Ultimately, this service gives solutions that improve opportunities and quality of life for the citizens of both cities. 

The consortium led by CAF group,  and involving Isolux, Thales and Azvi, has provided the trains and its systems. Particularly, the inteR-urban train Mexico-Toluca will be supervised and controlled from the new Operational Control Centre (OCC). The core of the OCC is in the Garage and Workshop Administrative Building of Zinacantepec. The OCC is where a complex informatic system is stored  and it manages all the trains operations, offering a secure, punctual and high-quality service to the users. This system has been designed and built following the highest demanding rules and newest standards of the world-wide railway market.

Geograma has contributed to the success of this ambitious project by developing the Geographic Information Window (GIW). The GIW, integrated within the OCC with the advanced control platform (NAOS – CAF Signalling), allows the railway technical support to check in real time (on a map) the global status of the infrastructure.

As a specialized GIS company, we have a wide experience of visualization and management of Geographic information, so we were able to provide an efficient and useful solution for the challenge.

Thanks to our experience, the company CAF Signalling trusted us for the development and integration of the Geographic information Windows (GIW) with the signalling systems.

With such a visualization system, the clarity and ease of the information might be the key to manage the issues encountered in the routes. Hence, the main challenge was to develop a very easy an intuitive tool, integrated with the existing synoptic chart, which allows the technicians to search and find information regarding wagons location, alarms or signals.


 The developed solution to reach the objective is based on two elements:

·      Web application to consult the information in a graphic interface

·      API to connect the new module with the pre-existing ones

The web application shows the geo-referenced information of the features in the field on a fixed cartography. This information is represented with layers, allowing the user to show or hide groups of information according to its needs.

This GIW is made up of the following elements

·       Map: main area that covers the whole window. On this map you can see all the selected layers from the legend.

·       Legend: this visual area contains the list of the layers of the infrastructure. From this tool the user can show/hide the information. These layers can show static information (buildings, facilities, tunnels, signals, etc) of dynamics (trains, alarms, catenary).

·       Search: Smart search box, where the user can easily find any geographic feature on the map.

The Geographic Information Windows (GIW) provides an API to establish communication with the synoptic chart, and update the dynamic information of the application: trains, alarms, etc.



Both companies, Geograma  and CAF Signalling believe that the advantages of a module like the Geographic Information Window will increasingly help  the management of such an important line of transport like the one that joins Toluca with Mexico city.

The integration with the current systems, and the functionality of this new interface, allows an easier management of any kind of incident to help guarantee the success of the new transport line.


From the beginning of the project, the collaboration with Geograma was a work that added a great value to our solutions. The knowledge of the Geograma’s team, and their implication in the development were the key for the success of the project.
