Let the people initially on the train be 'x'.

19 people got off the train --> x - 19

17 people got on the train --> x - 19 + 17

Remaining people on the train = 63

Therefore, x - 19 + 17 = 63
                  x - 2 = 63
                       x = 63 + 2
                       x = 65

Verification:
65 - 19 + 17 = 63
65 - 2 = 63
63 = 63
