I took the liberty of looking up the builder's specifications for the four tender engine classes pictured in your first post; I particularly noted the details of the 1891 engines (the american types and the moguls). Those were ordered at the same time. They use a number of common items, including the same tender, virtually the same size boiler tubes, same headlight, same make of injectors (sellers), etc. Both have relatively large boilers and fireboxes for their sizes giving the impression of free-steaming engines with good power. They were doubtlessly attractive machines as-built, painted olive green with a fair amount of line trim and crystal plate glass. There's a peculiar note written in the specification for the 2-6-0's, "Last moguls roll very much, remedy this..." with additional commentary indicating the equalization of the front drivers and lead truck was to be changed to improve the ride relative to the earlier machines**. The american type was good for a bit over 8,000 pounds tractive effort, and the mogul, just under 13,000. Those are about average for their types and gauge circa 1890.
Do you know the rail weight of the railroad in those days? I ask because the 1900 ten wheeler and1903 consolidation were much heavier, the 4-6-0 about 50% heavier than the earlier mogul and the consolidation, heavier still. This implies the railroad was either initially laid with heavier rails than necessary (which was sometimes done) or upgrades/new construction occurred during the years between the two groups.
Being ordered at different times by seemingly different entities, the ten-wheeler and consolidation types do not exhibit the same extent of component standardization that the earlier engines had, as they differed in most details. Both of these later classes were utilitarian in appearance, plain black with no striping as is plainly evident in the builder' photograph of the ten-wheeler above. Both represent good-size engines. The 4-6-0 made over 19,000 pounds tractive effort and the consolidation, almost 25,000.
Good stuff, there isn't a lot on Newfoundland's railways in their early days out there, so it's appreciated.
**Numerous other railroads, including the D&RG, had issues with insufficiently smooth tracking at speed on short-wheelbase mogul types, which was also touched on in the thread about the 2 foot gauge Mexican engines.
