(a) Outline map of Nigeria

Key: solid black line = railway from Ibadan to Kano; thick red line = main road from Port Harcourt to Lagos.

(b) Contributions of transportation to the economic development of Nigeria

1. It enables the movement of people, raw materials and finished goods between areas of production, markets, industries and ports.
2. It promotes internal and international trade by linking producers with consumers and export outlets.
3. It creates employment for drivers, railway workers, mechanics, dock workers, traders and other transport-related workers.
4. It opens up new areas for farming, mining, settlement and industrial development, thereby encouraging the growth of towns.

(c) Problems limiting rail transportation in Nigeria

1. Many tracks, locomotives and coaches are old, poorly maintained and liable to frequent breakdowns.
2. The rail network has limited coverage and does not serve many parts of the country effectively.
3. Inadequate capital, poor management and shortage of spare parts and skilled technical personnel reduce efficiency.
