Re: Angled cylinders on cane locomotives

   The sliding, oil covered surfaces of piston rods and crosshead guides are the most vulnerable parts to dust and subsequent wear on these locos, and so, any way of getting them higher up, out of cane trash and dust was highly desirable.
  The unfortunate effect of angled cylinders was a tendency for the engine to 'waddle' when working hard, and on some of the very small engines, the effect was quite onlookers, not for the crew!

I understand also that the reason for angled cylinders was to give better clearance particulary for sugar cane locos working on branch lines and maybe portable track. The very early Fowler locos had indirect drive that did the same job in a more complicated way for the same stated reason. Later locos by Fowler were angled direct drive which did a similar thing but in a a simpler way. These early very small locos were designed to work on portable track. In most places animal or human power and later tractors was used to get the loaded wagons to the 'main' line. So maybe the need for cylinders to be out of the way changed when their use became more 'main' line focused.

I've a question that I'm unable to answer from an overseas modeller
who is attempting to build the Fowler PETRIE 0-4-2 in 7/8" scale. His
query obviously relates to a number of small sugar cane locomotives:

Lastly, I have yet to find anyone to give me an explanation of why the
cylinders on many of these locos are set at an angle. The only thing
I have heard so far was it was for better clearance; to set them a bit
higher relative to the wheel c/l on small drivered locos.
Any help appreciated.

Thanks and best wishes,
