The 91 year old was crossing the tracks at Langwedel station in Lower Saxony on Friday, pushing her walking frame in front of her, police report.
But, to her misfortune, it was exactly at this moment that the Intercity 1933 came flying along the tracks at a speed of 160 km/h.
The driver heard a bang under the engine and assumed he had hit a wild animal.
When he went out to check the damage at his next stop in Verden, however, he was shocked to find the mangled remains of the old lady’s zimmer frame.
According to police, he fell into such a state of shock that he could not carry on driving the train.
At the same time, a driver travelling in the other direction noticed a body lying on the tracks.
Emergency services feared the worst, but when they arrived at the scene they found the nonagenarian had only suffered light injuries.
Everyone was “overjoyed”, police reported.
Officers listened in astonishment as the old woman told them she had been taking this short cut over the busy tracks for years - despite the fact she uses a zimmer frame.
An ambulance brought her to hospital as a purely precautionary measure.
She was able to survive the horror episode by keeping a cool head.
When she saw the train approaching she threw herself flat on the tracks, and the vehicle travelled straight over her.
According to police the old woman pulled off a feat that “is normally not possible”.
Someone lying on the tracks would normally get sucked up by the train, or their clothes would become entangled in the lowing-hanging parts of the undercarriage, police said.
