São Paulo Metro’s Line 15 Monorail Project
Paulo Sergio Amalfi Meca, head of construction at Companhia do Metropolitano de São Paulo, provides a detailed overview of the Line 15 monorail project and explains its importance.
Mr. Amalfi explained that the Monorail system was chosen as the preferred solution because:
1. Monorail provides the same quality of service as conventional metro
2. The monorail system produces less polluting emissions
3. Excellent operational performance
4. Conforms to all relevant regulatory requirements
5. The track doesn’t require a broad footprint
6. A lower of number of expropriations are necessary to complete construction
7. Lower cost of system implication
8. Supports the construction of sharper curves and steeper inclines in the track
Project Overview: Line 15-Prata
The initial proposal to ease congestion in the west of São Paulo was to construct a dedicated bus lane, which would use diesel vehicles to transport 250,000 passengers a day. This plan has now been revised, and the solution will now be an electric monorail system that will be able to serve over 550,000 passengers per day.
The Line 15 monorail system will operate 54 trains, with 7 cars per train and a train capacity of 1,000 passengers per train. Operating a CBTC/UTO driverless system, the projected interval between trains will be 75 seconds, while the operational interval will be around 90 seconds. Stations are elevated above street level and a passenger walkway will be constructed to enable evacuation in the case of emergencies.
The tracks are currently being constructed between 12 and 15 metres above the ground, while the footprint of structure is very narrow, allowing the monorail system to run along the central reservation of the cities major avenues. This ensures the viability of the system, especially in densely populated cities such as São Paulo.
Many of the stations will also be constructed along the central reservations of avenues, with escalators or stairs providing accesses to the platform. The technical and operational rooms are situated in the legs of the structure, minimizing the cost and of land acquisition in a very expensive city.
The rolling stock will be provided by Bombardier Transportation and is currently under construction in the Hortolandia factory in Brazil. The cars will be spacious and windows will ensure a great deal of natural light.
