Unlike the Walschaerts and Baker systems, the Southern valve gear dispensed with the combination lever which transmitted some of the crosshead motion to the valves. As with those systems it used a return crank on a driver (instead of the eccentrics used by the Stephenson valve gear). The return crank attached to the eccentric rod, which hung ...
Walschaerts. W.G. Bagnall claimed that Bagnall–Price valve gear eliminated some of the complexity of the Walschaerts gear, specifically the combination lever and return gear; this in turn meant the externally mounted gear had greater ground clearance which was an advantage in industrial locations where lineside obstructions could damage the gear of passing locomotives.
