The Nigerian Railway Corporation NRC has introduced the new 'first-class' trains in order to reduce conjestion on the roads and to banish the image that trains are for those who can't afford to travel to their destination by other means.
This is definitely a step in a positive direction, and should be embraced and encouraged.
The locomotives were delivered in response to the signed agreement between the Nigerian government and the company GE Transportation.

The road infrastructure of the city of Lagos is highly lacking in the basic framework that could make it easily navigatable and 'public' friendly, hopefully the trains will remove some of the 'pressure' placed on the roads.
In its success, I believe that the roads will be addressed, however if this is not the case, at least the roads will be alleviated of some traffic.
