WAGR M class (1911)
The M class was built by Beyer, Peacock & Coy from 1911 to 1913, they had recently negotiated the exclusive production of Garratt articulated engines manufactured out of the UK. The WAGR were the first to order Garratts of such size and quantity for a state system, playing a vital role in the global success of Garratt locomotives, the WAGR being somewhat of a trailblazer in this respect.
