A MASTERPLAN TO DEFINE THE INFRASTRUCTURE
IMPROVEMENTS FROM 2014 TO 2025.

ALGIERS

Alger is the capital and largest city in Algeria, rapidly growing and incorporating adjacent towns in an agglomeration of about 3,5 million people.
The Algerian Infrastructure Manager, SNTF, is completely renewing and improving the existing network to offer fast and efficient connection among the major cities.
The region around Algiers is the core of these ambitious plans, that include a new high speed line from across the region and other improvements that will allow to quadruple regional and sub-urban services.
In order to right-dimension the network avoiding ineffective expenses, LIFT planned the infrastructure layout and a timetable draft and tested them using micro-simulation iteratively, to obtain an optimal equilibrium between number of trains and reliability expectable in real operations.To start taking advantage of the new rolling stock and of the first interventions to be put into service, LIFT also developed a short-term regular interval timetable that allowed doubling the number of services on the existing network.

Our tasks:
- Preparation of the infrastructure model;
- Definition of a long-term timetable draft;
- Definition of a short-term regular interval timetable;
- Development of the infrastructure and interlocking layout;
- Stochastic micro-simulation of all scenarios.
