The Delhi Sarai Rohilla-Bikaner Express derailed at 2:52 am on the Zerpur-Satnali section after a tractor collided with it, causing four of its wheels to go off the rails, the spokesperson said.
No injuries have been reported, he said.
"The train was provided with fresh power and it left the site at 5:25 am for Bikaner," railway spokesperson Anil Saxena said.
This is the second incident in less than 10 days where unauthorised vehicles have caused accidents.
On November 24, a bolero, carrying a marriage party, was hit by a local train in Uttar Pradesh.
