Metropolitan
Definition of metropolitan facilities, tramways, trolleybus, rack railway in any of its electrification systems: overhead contact line, rigid, retractable catenary, etc.
Within the railway facilities there is metropolitan transport, such as trams, subways, trolleybuses, rack trains, etc., whose philosophy regarding the electrification system may be closely linked, but its detailed engineering differs in the system itself to use, either overhead, rigid, retractable catenary, etc.
Voltrain has the experience for the development and execution of projects of all these metropolitan systems, from the most generalized scope, to the highest degree of detail.
