Police have confirmed that the post mortem is due to be carried out to formally identify the deceased.
Translink meanwhile confirmed that the Londonderry line reopened last night after remaining closed for most of the day as a result of the tragedy.
The line was closed on Tuesday morning and a train remained on the tracks for much of the day as forensic officers, PSNI, ambulance personnel and Translink Infrastructural Division staff attended the scene.
Cordons were erected at the bottom of St Columb’s Park and at the pedestrian Waterside Greenway, which runs between the rail track and the eastern bank of the River Foyle.
