   It's a relatively conventional Beyer-Garratt locomotive.  The concept is that   
   the boiler is suspended between two engine-units, the "rear" engine unit   
   carries the fuel and some water, the "front" engine unit has a water tank (to   
   supply the boiler, I say    
   front and rear in quotes because the locomotives are designed to be used   
   equally well in either direction), and there is no separate tender.  Ohe   
   benefit is that the boiler has no wheels or running gear beneath it, so it can   
   be of large diameter, and can    
   sit lower than would be possible with driving wheels beneath it, which is   
   useful for stability on narrow gauge track.  In general it provides for a   
   large and powerful locomotive on a light axle loading that can cope with   
   narrow gauge track with tight    
   curvature.
