The Class 646 locomotive, as photographed in July 2012 not long after arrival. This locomotive was obtained on a whim like the GE 20T Switcher, and was bought with the intent of operating a 'world' fleet of locomotives from most countries, selecting the most historically relevant engines possible - this including the Class 646 from Italy. Manufactured by Lima in Italy, appropriately, the locomotive is more basic than the other engines but makes up for it with a charm of its own in terms of its appearance.

The side profile of the locomotive, showing its unique shape - boxy, but decent. The motor, an old Lima 'Pancake' motor, is showing its age but still runs in a fair condition, propelling this locomotive around the line with some speed. In time it may require a remotoring to be efficient as the other engines; for now the locomotive works fine.

The cabside, where the simple shapes and livery stand out in sharp relief and are highlighted well.

The roof pantograph on the front of the locomotive, standing tall and proud.

The articulated section of the locomotive, showing its flexibility as an articulated design.

The rear cab of the locomotive.

The rear of the locomotive - though the paintwork is faded and the quality is lesser, the engine is a survivor and still stands strong.

The front of the locomotive, showing its headlamps (directional) and profile. Overall this is a locomotive that runs reasonably and looks reasonable, yet belies more than it lets on.
