What is the difference between a 0-6-0 & 2-2-2?

Just looking at the RS30 Crash Train set & I thought it was a 0-6-0 - turns out - it is a 2-2-2 - see photo below :-

Also it looks pretty much the same as the 2 0-4-0 Loco's below but just been stretched a bit just to fit the extra 2 wheels in the middle!!! :-

Thank you 🤔🚂🚂🚂

If you take the coupling rods off the jinty and it drives to the second axle it would become a 2-2-2. The numbers refer to the front carrying wheels, driving wheels and rear carrying wheels respectively. There is lots of information on this, usually in Hornby catalogues.

Some independent light railways did this to their locomotives so an 0-6-0 could become a 2-4-0 or even a 2-2-2 as they took the rods off them for whatever reason.

I believe there was one occasion where a 9F was sent back for repair with the rear coupling rods removed making a 2-10-0 into a 2-8-2. A Garratt with two carrying wheels and six driving wheels would be 2-6-6-2.

On the continent the numbers refer to axles rather than wheels so a French pacific, rather than being a 4-6-2 would be a 2-3-1.

The two 0-4-0 locos are repainted short Thomas and Percy models in early BR colours and made up or re-used numbers. The Thomas with an Ex-LMS number and the Percy with an Ex-SR number.

I don’t believe that the real Jinties ever had mixed-traffic lining although since the early Tri-ang models they have been produced with it.

I've noticed quite a few mistakes like that on the Hornby website, and that's just what it is - a mistake.

0-6-0 means all wheels are driven, connected by coupling rods. 2-2-2 means there are two leading wheels, two driven wheels and two trailing wheels, none of which are attached to eachother by coupling rods.

The 0-6-0 loco included in the Crash set is a Jinty, of LMS design, whereas the second loco is one of the standard Hornby 0-4-0s. The last loco is a recolour of Percy from the old Thomas and Friends line. They all happen to be in BR black.

Hope this helps.

On an aside, I've noticed the 0-4-0s are now being listed as DCC Ready and with 5-pole motors, see the class 06 in the Network Traveler set for example.

Thank you Rana & GWR Fan - so it depends on how the wheels are connected with each other with the coupling rods then - If all connected then it's a 0-6-0 but if only say 2 on each side then it's a 2-4-0 - OK I've think I've got it now 🙂🚂🚂🚂
