The ten-wheeler from America is the very familiar 4-6-0 wheel arrangement we see here in the UK. Take a look at the LMS Black 5s, Jubilees, and the GWR King, Castle, Hall and Manor engines. These engines all have the same wheel arrangement as each other. Thus, they all have four bogie or pony truck wheels at the front, and six bigger driving wheels in the middle. There aren't any trailing wheels behind. The engines are all 4-6-0 Tender Engines. The bogie or pony truck wheels at the front not only spread the weight of the engines, but also guide them round curves in the track. Hope my knowledge of my favourite wheel arrangement is helpful to all those out there in the world of railway modelling.
Another variation that may confuse some is a loco like the Hush Hush W1 being correctly described as a 4-6-2-2. This is due to the trailing wheels not being in a bogie. Similar with the early broad gauge Iron Duke and Rover classes being recorded as a 2-2-2-2 in a HMSO Science Museum booklet I have due to leading wheels being mounted in a rigid frame and not a bogie. Probably less confusing to call them a 4-6-4 and 4-2-2 though.
Been searching a while for such a tutorial. So glad I stumbled upon your video. Many thanks for simplifying this topic that has had me intrigued for some time now. Subbed! Wishing you the best, from Sri Lanka 🇱🇰
No, Bo represents a 2-axle bogie with both axles independently powered. The Warship hydraulics had a B-B wheel arrangement as both axles were not independently powered.
Surely the front bogie wheels are leading wheels? Tenders would only be included in the Whyte notation system if the loco or tender was fitted with a booster set like some of the NER Atlantics which became 4-4-4-4 tank engines, until the boosters were removed to become Atlantics again. The Southetn Railway adopted for a while a loco numbering system based on the wheel arrangement system used foe diesel and electric locomotive wheel arrangement classification system.

The 'Ponies' at either end assisted in 'Guiding ' the larger Driving wheels around corners by stopping them 'Jumping'

Nice job Dave. all the best ,keep up the good work.
In addition to the + sign to indicate a steam loco like the Garrett the Class 76 was Bo+Bo.

Great video Dave very interesting and informative. Thank you.

So James the Red Engine is a 2-6-0?
Question: If the leading wheels can slide from side to side, then how can they guild the train in curves?
Because the wheels' flanges guide the engine across the curves
@@Combes_ If they are not fixed on the frame, their fangles can only guide the wheel set itself.
@@henrywang3977 you know what I mean
What is a Atlantic
From research, I gather there has never been a British Class locomotive with a Do-Do wheel arrangement, unless someone knows otherwise?
Hi J, there's nothing that comes to mind here either so I think you're correct! - Dave
