The train reportedly stopped shortly after it left Howrah station, owing to possible chain pulling and the guard went to inspect the situation.
On finding that the air pressure in the brake system had dropped, he started mending it, when the train started moving again with the hapless guard holding on to the pipe, as shown in a video clip shot by a bystander.
"It is possibly a case of miscommunication between the driver of the train and the guard," Ghosh said.
The train was made to halt by RPF personnel alerting passengers to pull the chain, and the guard escaped unhurt, he said.
