Thousands of Nigerian railway workers have begun a three-day strike to push the government to improve their welfare.

The strike is likely to disrupt services in some of the busy stations, including the railway line that links the northern Kaduna state to the capital, Abuja.

The sector is expected to lose about 90m Naira ($200,000; £148,000) during the strike, the Punch newspaper has reported.

Much as trains are used by many Nigerians, the road transport remains the most common mode of transport.
