What locomotive is this?

What engine am I describing?

"A three-unit 100km/h eight cylinder freight locomotive, able to haul a 10,000 tonne load, with a 1-E3+3C-KT-C3+3E-1 wheel arrangement. Under the Whyte system it would be described as a 2-8-6+6-6-6+6-8-2 wheel arrangemnent. An enclosed body with semi-streamlined outer ends contained, in each end unit, a 20 atmosphere (300 psi) superheated parallel boiler with twin blastpipes side-by-side, and 18.6 sq m grate fed with mineral coal by an automatic stoker of American pattern. The five coupled wheels beneath each were of 2m diameter, with two outside high-presure cylinders 870mm x 900mm, having piston valves controlled by Heusinger valve gear (essentially the same as Walschaerts, but designed independently in Germany by Edmund Heusinger von Waldegg; both were introduced in 1848-49).

The centre unit contained the condensing apparatus and at either end bunkers holding 50 tonnes of coal apiece. 50 cu m of water was stored beneath and between the condensers with a communicating corridor through the centre of the tank. All this rode on two six-coupled engine units back-to-back in a rigid frame, each again equipped with 2 m diameter wheels and Heusinger valve gear, which in this instance actuated the piston valves of 1225 mm x 900 mm low-pressure cylinders. The reversing gear was powered by electric motors. Each boiler had a heating surface of 812 sq m and 300 sq m superheater area; at 20 atmospheres pressure the steam temperature was 400 deg C."

Don't bother guessing - either you've come across this design or, if not, you won't stand a chance of guessing.

No. And no. It was a real, serious design.

Sounds a bit like a Big Boy to me or something from China.

Could it possibly be Chaplons designed-but-never-built-150mph-capapble Garrett? Sure i've heard something about this thing before, said it was a bit unorthadox...

Must be 1 hell of a garrett if it is that like. Especially with a wheel formation of 2-8-6+6-6-6+6-8-2

Sounds like one of those South African beasties.......

Sorry, did i say Garrett? Couldn't think of a better word, perhaps, 'Articulated Locomotive' would be better? Oh yeah, and it was streamlined as well...

It's a pug!

Oh the glory days of a 2-8-6+6-6-6+6-8-2 saddle tank shunting the yards in Yorkshire

No Martin. I refuse to build that one!

100Kmh thats 62Mph

It looks as if it has 3 different traction sets (look im not into locomotives) so yeah one of they massive south African Garetts...Streamline front and back...still sounds liek a Garett with the curved front thing on both ends....what else did he say...automatic stroker...again soudns like a garett, not a hope in hell of me being able to do any more than imagine a huge garett...your going to have to post some pictures.....Was big boy streamlined?

He's probably now going to tell us that it was a Thompson . of 3 Gresleys.

Brunel's design for the Atlantic Tunnel locos?

Or something by Bulleid?

Martin, why don't you just tell us to put us out of our misery?
