The Lagos-Kano express train service is to recommence by the end of July, according to the head of the Nigerian Railway Corporation (NRC).
Adeseyi Sijuwade said that the final checks were currently being carried out by railway engineers ahead of a full resumption of services between the southern port city of Lagos and Kano, located some 1,200 km away in the far north.
The six-phase modernisation project, which began in 2006, was undertaken by the China Civil Engineering Construction Corporation (CCCC).
A number of bridges along the route have been replaced with larger structures and anti-flood culverts were upgraded.
The reopening of the route had been delayed twice recently due to heavy rainfall which damaged some facilities on the line.
