Police sources said the girl, who was returning to her Tamluk home in the Howrah-Midnapore Local, rushed to the door of the compartment to escape the alleged molestation bid by some youths and jumped off the train near Panskura in West Midnapore.
She was rescued by locals and taken to Tamluk Hospital in neighbouring East Midnapore district. Her condition was stated to be serious but stable.
The girl's family in its complaint has alleged that the molesters attempted to kidnap her.
