AT A GLANCE

TISSEO Voyageurs commissions the engineering firm EGIS RAIL for the renewal of the CR1/CR2 switch on the Toulouse metro line B (“Métro Pneu”) of Toulouse. This renewal was necessary, as the wooden sleepers installed 20 years ago could not withstand the maintenance work on the switch.

The engineering office was looking for sleepers that would be resistant to different temperature fluctuations and resistant to mould. The sleepers should also be able to withstand a high degree of machining and be very durable.

The STRAILway polymer sleepers met the expectations exactly.

The EGENIE company was commissioned to carry out the conversion work and required a total of three weeks. First the workers carried out a pre-assembly to install the STRAILway polymer sleepers and the iron parts of the switch.

In order to fit the sleepers into the guide rail and the tracks and the other elements, more than 400 drill holes were required. This was the only way to ensure the necessary mobility could be guaranteed.

The switch was then divided into three parts (10 to 15 tonnes per part) and inserted into the fixed track (after regulating the geometry of the switch, resin was poured into the openings).
The installation went smoothly.
