IF ! this loco had been a success, I wonder how many would have been built ! and in what color, Green or Blue ??

This artist's representation seems to provide the answer to what colour:

looks very smart to me

EDIT: Just noticed there is a debate about this very picture on page 1 of the thread

Blackout if you read my post you would now about that green livery

I came across it after I posted

I bought an early copy of OS Nock's "British Steam Railway Locomotives 1925-1965" and was rather chuffed to find two fold out diagrams of 10000 - one the GA drawing and another of the make up of her boiler. Also some plates showing LMS Fury under construction. Well worth a look for those interested in the W1.

Might not have been too heavy.
What was the axleload of the the loco compared to others?

The operating weights diagram shows 62T 10Cwt distributed near equitably over the coupled wheels, and a further 46T well distributed over the carrying wheels. Since the design intent was for operational equivalence to the A3 that stacks up. I would imagine that there was more difficulty in estimating the weights with an unconventional boiler design, so those numbers are probably to be taken with a pinch of salt.

But unless the civil engineer had some good reason to believe those weights were seriously wide of the mark, there would be no real problem with allowing this loco to travel slowly on track and structures normally restricted to somewhat lower loadings. The factors of safety in design were generous, and with a minimal dynamic augment obtained by running slowly during a single visit no significant damage would be done. It is in the repeated cycling of load/unload combined with small deteriorations to the structural components between maintenance intervals, repairs and renewals where the trouble occurs; and especially when resonances occur with rapid load/unload cycling, then things can go to pieces very fast...

When rebuilt the operating weight diagram actually increased by circa 5T, likely the greater water mass in a conventional boiler compared to the water tube type accounting for this. Most of the increase went onto the coupled wheels, shown carrying the combined usual 66T for the final iterations of Doncaster pacifics.

Not too sure where this was taken in this old cutting.

Saw this thread and it reminded me of a live steam model built by one of my fellow club members... a fine piece of engineering...

Not much help, but the signal arms forming the gantry's array are all of NER type.

Nice model. Does it have a water tube boiler?

hi dave

Afraid I can't remember, I do recall some talk of the boiler being unusual and knowing the builder personally I'm sure he would follow full size as much as feasibly possible but whether that involves a miniature of the boiler prototype I don't know, suspect it would need modifying in some way, less tubes of larger size, just like a standard miniature boiler. I'll try to find out next time I see him.

Thanks for that Pete.
Just comparing colours on this page, I prefer the blue, maybe a bit darker than the model!

hi Dave..blue?.....IIRC it's more a battleship grey..admittedly not showing very well in the photo....I,ll try to get a better picture if the owner brings it down the club again.. he's not a young chap so may not bring the larger type loco's often...I'm on steward duty on the 20th, if he's there I will try to get more info on his model then,,

It's a beautiful loco when viewed from certain angles, but, for me, the cab appears to be an afterthought and the tender doesn't match the loco. I always had a soft spot for 60700 as she became. First 'copped' in the late 50s at Grantham on a van train.
