Advantages
- High efficiency at high speed.
- Far fewer moving parts, hence potentially greater reliability.
- Conventional piston steam locomotives give a varying, sinusoidal torque, making wheelslip much more likely when starting.
- The side rods and valve gear of conventional steam locomotives create horizontal forces that cannot be fully balanced without substantially increasing the vertical forces on the track, known as hammer blow.
