The FG is set to fully launch the Nigerian Railway Corporation (NRC) e-ticketing platform next week.
The NRC says the 24 coaches would run 16 daily trips when operations commence next month.
Amaechi said that 560 Chinese and 20,000 Nigerians were hired to work in the construction of the Lagos-Ibadan rail.
Okhiria disclosed that NRC will not wait for all the stations to be ready before starting operations.
The government approved the increase due to the fact that the train will be conveying half its capacity.
