The minister stated this on Monday on a national television programme.
Amaechi said this is the only addendum the President Muhammadu Buhari administration made to the rail transportation 25-year masterplan it inherited from the previous governments.
The minister said while the Lagos–Ibadan standard gauge will terminate at the Lagos Wharf, the Itakpe-Ajaokuta line, which was to terminate at Agbor, has been extended to Warri.
He added that there was an approval of a deep sea port in Warri.
According to him, the Lagos-Calabar coastal rail line being proposed by the administration will link the Warri, Calabar and Port Harcourt ports.
Amaechi also said the Buhari administration was working at linking the Tin Can and the RORO Ports in Apapa by rail.
But the minister said linking the new Lekki Deep Sea port by rail with other parts of the country would happen in the future.
He added that the Buhari administration will begin work on the $5.8 billion (about N2.8 trillion) Ibadan to Kano rail project once the Federal Government gets the loan for it.
Amaechi said the Buhari administration also remained committed to begin work on the Eastern line – stretching from Port Harcourt to Maiduguri, the Borno State capital.
The minister noted that if this could be accomplished, the current administration would have recorded a milestone of linking all state capitals by speed train network.
Shedding more light on the Lagos-Ibadan standard gauge, Amaechi said the contractor, contrary to its earlier work schedule, is yet to deliver on the four major stations on the route.
The stations are at Apapa, Ebute-Metta (both Lagos), Abeokuta (Ogun) and Ibadan (Oyo).
The minister explained that of the nine minor stations, only Kajola (Ogun), which was the model, was nearing completion.
Amaechi decried the negative impact of ports congestion to the projections, saying the equipment that arrived on the nation’s waters since December had not berthed due to the congestion.
