    MSWJR 16 was not built for a South American Railway. This was simply made up and printed many years ago. The locomotive, as has been discussed in these pages a few times, was built to the drawings of the NSWGR B205 Class Locomotives, introduced in 1882 and the last one bowing out of traffic (on a colliery line) circa 1972.

    Beyer Peacock order lists show that the MSWJR ordered it and the second one themselves, as new locomotives.

    Many thanks (that's why I use the tag line I do!). OP amended accordingly. :)

    There's 2 7 1/4" gauge 59th class locos in the uk, Mount Kilimanjaro (not me driving in that shot, but I was one of the loco's drivers that weekend at the Moors Valley), which is now based at the Rugby MES, and Mount Kenya, which is, I think, back at the NRM now, albeit still in bits from a part completed overhaul.

    I understand there is a 3rd model in Belgium as well, but I'm not 100% sure about that.

    Certainly among the heavier 2-10-0 types, comparable with German Class 44.

    I can imagine a British equivalent being a Duchess or P2 boiler on a 2-10-0 chassis. But even if we had use for such a machine, could that boiler size fit over coupled wheels within British loading gauges?

    And if it could, it seems loading gauge would be as much, if not more of a problem than Riddles found, when designing the 'standard' 8P.

    Add the problem Gresley's P1 highlighted. It's all very well being able to start and run humongous trains, but unless lines, loops and sidings can cope with them, there's really no point.

    Indeed, only with the strengthening of rolling stock and of infrastructure have heavy trains been short enough to manage...

    Was this Standard Gauge, or 5'6" Gauge? I have a feeling the latter, in which case the loading gauge would probably have been bigger than those of the Home Railways, enabling a larger Loco with a higher TE.

    Had to trawl a page either side of the outline drawing for context. To my mind, the proportions give the design a decidely West African look (Cape Guage, Ghana/Nigeria)

    Thank-you for posting this interesting 4-8-4 loco design. It dates (1931) from the period when Chapelon was greatly improving the performance of the French Pacific designs, which possibly reduced the need to build much larger engines. The design shown, with axle-load of 23.5 tonnes, was larger and heavier than any of the 4-8-4 designs that were actually built in Europe - German Class 06, Soviet P36, Spanish 242F and Chapelon's 242A1. I wonder if it could have matched the performance of 242A1?

    Of course, there were American 4-8-4s that were much bigger than this.

    Great to hear that someone liked it. Thanks for your added information bluetrain. :)
    I`m not an expert but I`m pretty sure that it would never have been near the performance of any of Chapelons masterpieces! :)
