Three bogies of a Karachi-bound goods train were derailed in Deharki on Thursday but no injury was reported, reported 24NewsHD TV channel.
The goods train was going to Karachi from Punjab.
Even the driver could not know that the bogies of the moving train had derailed and continued to travel towards its destination.
When the train reached Mirpur Mathelo, the railway employees informed the driver about the derailed bogies.
As soon as the freight train returned to Deharki, the process of connecting the bogies was started.
The movement of trains on the down track has not yet been restored.
