:f:

If they really had to do away with the superb pioneering flanged-rails ...





... they should have at least used the proper RP25 tire-coning on the wheels ! ;)



:doh:

In 1802, Trevithick built one of his high-pressure steam engines to drive a hammer at the Pen-y-Darren Ironworks in Merthyr Tydfil, Mid Glamorgan .
With the assistance of Rees Jones, an employee of the iron works and under the supervision of Samuel Homfray, the proprietor, he mounted the engine on wheels and turned it into a locomotive.

In 1803, Trevithick sold the patents for his locomotives to Samuel Homfray.
Homfray was so impressed with Trevithick's locomotive that he made a bet with another ironmaster, Richard Crawshay, for 500 guineas that Trevithick's steam locomotive could haul ten tons of iron along the Merthyr Tydfil Tramroad from Penydarren (51°45′03″N 3°22′33″W) to Abercynon (51°38′44″N 3°19′27″W), a distance of 9.75 miles (16 km).

Amid great interest from the public, on 21 February 1804 it successfully carried 10 tons of iron, 5 wagons and 70 men the full distance in 4 hours and 5 minutes, an average speed of approximately 2.4 mph (3.9 km/h).
As well as Homfray, Crawshay and the passengers, other witnesses included Mr. Giddy
, a respected patron of Trevithick and an 'engineer from the Government'.
The engineer from the government was probably a safety inspector and particularly interested in the boiler's ability to withstand high steam pressures.

The configuration of the Pen-y-darren engine differed from the Coalbrookdale engine.
The cylinder was moved to the other end of the boiler so that the firedoor
was out of the way of the moving parts.
This obviously also involved putting the crankshaft at the chimney end.
The locomotive comprised a boiler with a single return flue mounted on a four wheel frame.
At one end, a single cylinder
with very long stroke was mounted partly in the boiler, and a piston rod crosshead ran out along a slidebar, an arrangement that looked like a giant trombone.
As there was only one cylinder, this was coupled to a large flywheel mounted on one side.
The rotational inertia of the flywheel would even out the movement that was transmitted to a central cog-wheel that was, in turn connected to the driving wheels.
It used a high-pressure cylinder without a condenser, the exhaust steam was sent up the chimney assisting the draught through the fire, increasing efficiency even more.

The bet was won. Despite many people's doubts, it had been shown that, provided that the gradient was sufficiently gentle, it was possible to successfully haul heavy carriages along a "smooth" iron road using the adhesive weight alone of a suitably heavy and powerful steam locomotive.

Trevithick's was probably the first to do so; however some of the short cast iron plates of the tramroad broke under the locomotive as they were intended only to support the lighter axle load of horse-drawn wagons and so the tramroad returned to horse power after the initial test run.

Homfray was pleased he won his bet.
The engine was placed on blocks and reverted to its original stationary job of driving hammers.

In modern Merthyr Tydfil, behind the monument to Trevithick's locomotive is a stone wall, the sole remainder of the former boundary wall of Homfray's Penydarren House.
A full-scale working reconstruction of the Pen-y-darren locomotive was commissioned in 1981 and delivered to the Welsh Industrial and Maritime Museum in Cardiff; when that closed, it was moved to the National Waterfront Museum in Swansea.
Several times a year it is run on a 40m length of rail outside the museum.

Hi Jose :wave:



You know that muffled sound, you sometimes hear behind your HUGE stash of kits ? ???

You can't see where it's coming from, the acoustic-barrier is far too big for that.

But when the kit stack was smaller ...

... you remember, it was THE MRS. ! saying :- [whack]

That yard-work you were supposed to do last week dear ?

or ... Those shelves that still need putting up for my shoes ?

You think ...

... maybe, just maybe, just 1 more kit & it could be acoustically perfect !



;)



I had a look on eBay, as you do.

JUST TO SEE OF COURSE ! :P

I've already promised, absolutely NO MORE kit buying !!

But I saw a BARGAIN ! :)





It isn't quite 'mint in box'. :f:

Not started by the owner ...

... but opened by the mouse in his loft ! :shocked:

( The Mrs. musta told him to put all his kits up there )





He says in the eBay listing, that one of the loco wheels might have been eaten a bit.

Anyway ...

... just looking, what would I want with an obsolete rusting 19th Century death-trap of a contraption like THAT ! L:



:Crazy:



Si.

ANOTHER railcar:

http://shitty-car-mods-daily.tumblr.com/image/169694752656

Kind of crappy, but:

1) runs on rails

and

2) it IS odd...

Jose.

I like it Jose ! :P Sophisticated !!


Just need some animated LEDs ...

... and a cheesy driver figure ! ;)









Probably has electronic-ignition & runs good on regular gas. :cool:

No getting decapitated stoking the boiler like on the Trevithick contraption anyway ! :shocked:



;)

Another Trevithick model by 'Airfix'.

It doesn't seem to say on the box ...

... but I believe, according to some, that this is possibly 1:32 scale ?

( don't quote me on that though ! )








Photo from Google Images.
