Mogul Locomotive
Also known as Bissel Bogie, Carello Italiano or Zara Truck.
A locomotive that according to the Whyte classification is of the 2-6-0 wheel arrangement. Due to the cleverly designed front bogie, the Mogul 2-6-0 ran like a locomotive with a two axle leading bogie e.g. 4-6-0.
Giuseppe Zara designed a system that combined a leading axle with the first driving axle. With a slight amount of play allowed in the leading driving axle the result was a sort of leading bogie that allowed some rotation in curves. This is the Bissel bogie or 'Zara Truck' (known in Italy as the 'Carello Italiano').
