The deceased was identified as Puskar Goud of Jagannath Prasad area in Ganjam district and his 7-year-old injured son Karunakar.
"The son was tied to his father's waist in a cloth, indicating that it was a suicide bid. The man died on the spot while his son's legs were amputated," inspector of government railway police, Bhubaneswar Smruti Ranjan Kar said.
Some eyewitnesses said that the father-son duo was sitting in the waiting hall and later went towards platform no 2 where the tragedy occurred around 2.30 am, Kar said.
Karunakar was first rushed to Capital Hospital and later shifted to SCB Medical College in Cuttack.
"His condition is critical. We would conduct surgery on his legs after his condition improves," doctors said.
"We came in a bus from our home. Father jumped before a train along with me," Karunakar told mediapersons.
