Halte de Montaudran

Halte de Montaudran

The SYSTRA Modular Platform was first used in the Toulouse region in 2009, with the creation of Halte Galliani, a new 2 platform station in the Toulouse suburbs. Use of the Modular Platform system enabled the new station to be created in less than 4 months, from contract award to official opening by the President of the Languedoc Rousillion Region, and without affecting passenger traffic on this commuter line into Toulouse.

When the re-development project at Montaudran was being planned, the project team at SNCF Reseau in Toulouse used their experience to recognise the benefits that the SYSTRA Modular Platform system would again provide. Of particular interest to them, was the proven benefit of constructing the new platform behind a safety fence, away from the danger zone created by passing railway traffic. This enabled their safety resources to be employed on other projects in the region, and allowed the contractor for the Montaudran project, Connexion Rail, to plan his work independently.

For the SNCF project team view, as noted above, the principal reason was to avoid use of safety staff which was (at that time) a scarce resource due to volume of other projects they were trying to manage. The construction costs using the Modular Platform were the same as for a traditional system, but without the additional cost and commitment of safety staff.

A second reason was that, in the longer term (several years ahead) there is a project planned to install an addition track on this section of line, which will require a realignment of the platform track. The ability of the modular platform to be adjusted or moved will be a benefit.
