Triplex? You'll have to ask the ganger's permission for that!

 

I fancy doing some more photoshops if anyone has any suggestions of things that might have been? It's easiest if I can use a model manufacturer's side-on view as a base.

An A2/2 using all front wheel drive and for god measure make it also as 4-8-0 please?

*The streamlined 4-6-4 05 002 attained a maximum speed of 124.5 mph (200.4 kph) on 11 May 1936. This was in the course of a series of high-speed tests between Hamburg and Berlin. This speed was attained with a 200 ton train on the level and maintained for a distance of several kilometres. The locomotive suffered no mechanical defect.

Mallard's record (a blip on the dynamometer car trace, on a falling gradient, with failure of the middle big end) didn't start to be quoted as 126 mph until after the war. Draw your own conclusions.

As I read it mr Bulleid did not believe 126

The look of a potential GNR(I) 4-6-0 for Dublin-Belfast expresses might have depended on the date of it's introduction; if it was after the GSR 800 class that loco would have had a big influence on it and indeed it might have been a version of the 800.  Maedbh was after all Queen of Ulster IIRC, or was it Connaught? 

 

Before that, an enlarged V class might have looked something like a King Arthur, but this relationship has come up before in this thread.

 

There is an alternative, a fast Atlantic with big wheels.  There were some streamlined Belgian ones around at the time which might have been an influence; I'm not a fan of streamlining but they were quite stylish!

A three cylinder compound with smaller wheels had been smarter.

My impression (no more than that, I'm no expert on railways north or east of the GW) (or south of it for that matter) (and only to a limited extent of the GW), is that Raven's pacific wasn't a bad loco, certainly worth keeping until it was worn out.  It obviously never stood a chance against the Gresleys, because Gresley was in charge of locos on the new LNER and because his were very good engines indeed, but to say that Raven 'got into trouble' with his Cities seems a bit strong.  They were no faster or easier steaming than the Zs, but more powerful which was perhaps the most important thing in the immediate post WW1 period, as train sizes and weights increase but the timetables were held back to the post 'race to the north' agreements.

 

It was certainly more successful than 'The Great Bear'.

It will be interesting if someone can photoshoppe an A2/2 with frontwheel outside drive a la Raven A2.

It will not have the frame flex problems that Thompsons converted P2s had.

Ravens A2 pacifics proved beyond doubt, that three cylinder front wheel drive can pull trains.

i already did that a few years ago post 459 page 19 http://www.rmweb.co.uk/community/index.php?/topic/14790-imaginary-locomotives/?p=1827579

but since then ive realised that it i dont think it actually gives any benefits from an 8f you only save a few feet in length, it has less coal and water capacity compared to the tender and by making it a tank it also has a higher ton per axle which would probably restrict it from the branch lines ive envisaged it for. 

 

It can also  be made with a wide firebox over the small coupled wheels.

Much better framing and possibility of some sideway movement of first and last coupled wheels.

Based on  S160 it can be a formidable heritage locomotive.
