Parameters and characteristics concerning track construction

The delivery access should not traverse stairs; ramps are acceptable.

Once the cost of laying the track has been achieved, revenues can flow unfettered across the track nearly indefinitely.

In the spring of 1836 work began on the final stage of construction, the laying of the track and superstructure.

When deploying a long rail in the course of tracklaying, it is desirable that the position of the rail relative to the sleeper be controlled and corrected as required.

The main part of the works consists in laying the 15.5 km of track and nine new trams which will join the 21 already in service.

It includes the supply and installation of rail tracks and third rail, the expansion of a maintenance depot for a total amount of 36 million euros.
