No, but hitting a train head on will. As you get pushed backwards down the track at 60 mph you'll have undergone a net -120 MPH speed change, same as hitting a brick wall.
Hitting another car the same weight head on will get you 60-0, half as bad.
Hitting a parked car the same weight at 60 will be like hitting a brick wall at 30.
