BernardTPM Posted January 16, 2020 Share Posted January 16, 2020 2 hours ago, Tullygrainey said: Thanks for the link PaulRhB. Very interesting. The text describes this loco as a 1-1-2-1-1. However it also says "the outside road wheels were 3' 9" in diameter, and there was also a rail wheel of the same diameter in the centre of the axle" so does that make it a 1-1-3-1-1 ? I'd say a 2-3-2 as the front and rear wheels are each on a bogie and unpowered. Would you call a GWR Hall a 2-2-6-0? Of course not (and it would be technically wrong anyway) Link to post Share on other sites More sharing options...

There's only one powered axle and it has three wheels on it (Yes, that is odd in itself). I am not aware that Mr. Whyte used / at all. Then again, he didn't devise his notation for monorail systems. Given it was used on the Continent, perhaps it should be a 2A2, just counting the axles. 2 Link to post Share on other sites More sharing options...

Were the outer wheels actually fixed to the driving axle? They seem to have sanding gear so the answer is probably yes, unless the sanding is just for braking.

Hi Bernard, Quite right, my mistake, how about, 4/3-3-4/3 or perhaps (2/3)* 1.5-A*1.5-(2/3)*1.5 including wheels ? Madness !!! Gibbo. 1 Link to post Share on other sites More sharing options...

RMweb Premium Compound2632 Posted January 17, 2020 RMweb Premium Share Posted January 17, 2020 A little bit more digging shows that it is a six-wheeler... The Epping Forest trial has been mentioned elsewhere: 1 Link to post Share on other sites More sharing options...
BernardTPM Posted January 17, 2020 Share Posted January 17, 2020 The 1-1-2-1-1 description is wrong as the small wheels are unpowered. Whyte notation only counts front and rear wheels as one number regardless of being fixed or pivoted or combinations thereof, powered sets are noted between these, sub-grouped if coupled separately (as in, for example, Duplex locos). A 1-1-2-1-1 would be a Triplex loco! The trials were at Buckhurst Hill on the outskirts of Epping Forest. Link to post Share on other sites More sharing options...
Vanguard 5374 Posted January 17, 2020 Share Posted January 17, 2020 Shortly due to be married to a Pug chassis, however it’s not exactly a bash but more of a body swap. 8 Link to post Share on other sites More sharing options...
alastairq Posted January 17, 2020 Share Posted January 17, 2020 Reference tration shunter locomotives? There was a system developed which I believe used a IC tractor as a basis? The thing was guided by rails, but driven by [rubber?] tyred road wheels. someone somewhere has made a working model of this..... I know not where, how...or even, why....must strike a chord with someone on here? Link to post Share on other sites More sharing options...

Right now it’s a test print to see how the model builds up. 2 1 Link to post Share on other sites More sharing options...

When you get the kit sorted, give me a shout, as we've had a W6 on the Chosley & Wallingford Railway in recent years, and it's a gap in my model fleet!

CinderMonkey Posted January 19, 2020 Share Posted January 19, 2020 (edited) Blimey! Should've looked closer at the 2A2/1-1-2-1-1/2-2-2 whatever before I put it up here, I hadn't even realized that it didn't sit on 2 rails. What an interesting (albeit quirky) design...
