barcelona metropolitan transport (16860 words) |
 | The organisational model of public transport is based on the identification of three large sections or levels, whose basic characteristics correspond to elements and functions laid down in the ISOTOPE project of the European Union, which examines the regulatory framework for public transport in large cities. |
| The participation of public transport in the corridor/axes varies greatly according to the capacity of the infrastructures and the demographic importance of the capital of the axis. |
| In this period the urban transport of the eighteen municipalities of the MTE was metropolitanised, as were the municipal companies Transports de Barcelona, S.A. and Ferrocarril Metropolità de Barcelona, S.A. The third period began with the creation of the MTA as a consortium of the Generalitat, Barcelona City Council and the MTE. |
| Electric Traction (2793 words) |
| In England a patent was granted in 1840 for the use of rails as conductors of electric current, and similar American patents were issued to Lilley and Colten in 1847. |
| All that is needed to cause the car to move along the running rails is to supply current through an overhead wire or third "conductor rail." This wire or rail will serve as a "return" for the electric current to the dynamo in the power station. |
| This conductor rail was set one inch below the level of the running rails, and wooden ramps were provided at points and crossings to carry the collectors over the rails, thus avoiding a short-circuit. |
