The woman, who had boarded the train in Lucknow, was found unconscious on the tracks with several injuries on her head, legs and hands.
The incident took place late last night when the 60-year-old was about to de-board the Shatabdi Express at Ghaziabad station.
Two-armed robbers tried to snatch her purse containing jewellery, cash and mobile phone, and pushed her out of the train when she resisted, police said, adding that they managed to flee with the valuables.
Police have registered a case of robbery at the GRP station in Ghaziabad in this connection, and are scanning the CCTV footages to identify the miscreants.
