As a stunned loco pilot looked on, the Wadi station authorities alerted the next few stations to clear the signals and tracks. To prevent any possible mishap, trains coming from the opposite direction were also stopped, the officials said. As the electric engine ran, the railway staff gave a chase to it on a motorbike, managed to board it when it slowed down and stopped it near Nalwar but not before it had cruised for about 13 kms.
