No one was injured in the incident which occurred last night though the passengers were left panic-stricken and the train was delayed by four hours. Railway has ordered a technical inquiry into the matter, sources said.
The engine and two bogies of Jodhpur-Jaipur intercity express went ahead after its coupling opened and the remaining bogies slowed down and stopped due to automatic breaks, the sources said.
This happened three times near Gotan, Ren and Jalsu railway station.
A passenger, R N Pandey, said the train which left Jodhpur railway station at 6.15 PM reached Jaipur at 3.10 AM after a delay of around four hours.
