Variance of Special theory of Relativity from Galilian transformation

Velocity being not a constant (invariant) to Galilian transformation, it follows that if c be the velocity of train traveling in speed of light and a person in that speed train run along the direction of train with speed'v', then according to Galilian transformation, the relative speed of person should be

C'=c - v, but it is not true. Since c is the universal constant value and it should be same for all the state of motion. So we have C'=c. It means the speed of light became constant and for this their will be changes in time and distance.
