The three-day warning strike embarked upon by workers of the Nigerian Railway Corporation (NRC) has grounded train services across the country.

Passengers for the Abuja-Kaduna train services; Lagos-Ibadan, among others, were stranded on Thursday as railway unions down tools to press home their demands for improved welfare.

The Nigerian Union of Railway Workers (NUR) and the Senior Staff Association (SSA) had jointly issued a statement saying the warning strike, which commenced yesterday will end on Saturday.

They said their take-home pay was bad and needed an upward review. The unions said failure to address their grievances would be followed by protracted strike action.

There are concerns that the corporation would lose millions of naira because of the strike.

Meanwhile, the strike action will cost the NRC huge sums in economic losses daily. Checks by our correspondent showed that the NRC might lose over N57 million in the three days the strike action will last on the Abuja-Kaduna train service.
