PROJECT
Several rail crossings with elevated road structures will be built along the lines. A total of 35 pedestrian bridges will be constructed over the Nigerian Railway Corridor. Cable ducts and walkways, in addition to drainage system with two walls, will be built along different sections of the lines. Between Marina and Iddo stations, a combined 5km viaduct rail over the road and a cable-stay bridge will be built, linking the Red and Blue lines. Other infrastructures being built as part of the project include stations; signalling, control and communications (SC&C) systems; supervisory control and data acquisition (SCADA) systems; depot and workshop facilities; an operations control centre and a training facility for train drivers.
Rolling stock The urban rail network is anticipated to operate with 12-car trains, with more cars added according to demand. The maximum number of cars will, however, be limited to 16 a train. The 16-car trains will be 352m long and12-car trains 264m long. The cars will accommodate 300 passengers each. Signalling and communications The light rail system will employ the latest train authorisation systems, automatic train protection (ATP) and in-cab signalling in all of its lines. The wayside equipment will be minimised so that the drivers will not exceed the authorised movement limits. The ATP will help to maintain the speed restrictions set on the lines. To ensure that the signalling is available during power cuts, a backup power system will be fitted.
