They were also utilised to haul passenger trains, generally on branch lines where light track meant trains could not be operated at speeds unattainable for the B B class.

The light track originally was carried by a high trestle across the ravine leading to Cadjaw Pond outside of Honesdale, but in 1848, the trestle was replaced by a horseshoe curve.

With an axle load of, the A A had reached the design limits of size and power possible with a two coupled axle locomotive type with Victoria's relatively light track infrastructure.

But if they're in the nesting process, they're often not seen since they're the smallest of all sea turtles, and they leave light tracks in the sand that can quickly disappear ."

The light track contained 5 planes, which, except for the first plane at Honesdale, were positioned to take advantage of water power to lift the empty cars on the return trip to Waymart.
16.
The most significant change was the addition of a separate " light track " to return empty cars from Honesdale to Waymart, and the elimination of the plane for loaded cars at Prompton.
17.
The light track prevented the employment of the new narrow gauge diesel locomotives ( class 2095 ) which were introduced from 1958, so that the railway continued to operate exclusively with steam engines.
18.
The new light track contained a radius hairpin turn at Panther Bluffs which became known as the Shepherd's Crook, later providing spectacular views when passenger service between Carbondale and Honesdale was started in 1877.
19.
In normal service, their maximum speed was restricted to on account of the light track in use at the time and they were capable of hauling 280 tons at up long 1 in 55 gradients.
20.
At the end of the steam locomotive era they became virtually a universal class of mixed-traffic steam engine that, thanks to their low axle load could even be employed on branch lines with light track beds.
