Emergency services were called to the scene at about 15:35 BST on Sunday.
Eight casualties were going to Derriford Hospital but all were stable, South Western Ambulance said.
"At this stage we believe that a moving train drove into the back of a stationary train on platform 6 at the station, and we are currently looking into the circumstances to determine how this happened", British Transport Police said.
Police have advised people to avoid the station if possible, and said delays were likely for passengers travelling through the Plymouth area.
