Here are some images of Academy's 1/26 scale 1829 Stephenson Rocket.
I decided to go with white wheels, natural wood tender floor planks and a brown barrel. Though the rocket was basically all yellow I wanted a bit of contrast.

The
Rocket was the most advanced steam engine of its day. It was built for
the Rainhill Trials held by the Liverpool & Manchester Railway in
1829 to choose the best and most competent design. It set the standard
for a hundred and fifty years of steam locomotive power. Though the
Rocket was not the first steam locomotive, Rocket's claim to fame is
that it was the first steam locomotive to bring together several
innovations to produce the most advanced locomotive of its day, and the
template for most steam locomotives since. In fact, the standard steam
locomotive design is often called the "Stephensonian" locomotive.
Rocket
used a multi-tubular boiler, which made for much more efficient and
effective heat transfer between the exhaust gases and the water.
Previous locomotive boilers consisted of a single pipe surrounded by
water. Rocket had 25 copper tubes running the length of the boiler to
carry the hot exhaust gases from the firebox. This was a significant
development, as it greatly increased the amount of steam produced, and
subsequent designs used increased numbers of boiler tubes. Rocket also
used a blastpipe, feeding the exhaust steam from the cylinders into the
base of the chimney so as to induce a partial vacuum and pull air
through the fire. Credit for the invention of the blastpipe is disputed
between Sir Goldsworthy Gurney and Timothy Hackworth. The blastpipe
worked well on the multi-tube boiler of Rocket but on earlier designs
with a single pipe through the boiler it created so much suction that it
tended to rip the top off the fire and throw burning cinders out of the
chimney, vastly increasing the fuel consumption.
A closer view
Rocket
had two cylinders set at 35 degrees from the horizontal, with the
pistons driving a pair of 4 ft 8 in (1.42 m) diameter wheels. Most
previous designs had the cylinders positioned vertically, which gave the
engines an uneven swaying motion as they progressed along the track.
Subsequently Rocket was modified so that the cylinders were set
horizontally, a layout used on nearly all designs that followed. The
second pair of wheels was 2 ft 6 in (0.76 m) in diameter, and uncoupled
from the driving wheels, giving an 0-2-2 wheel arrangement. The firebox
was separate from the boiler and was double thickness, being surrounded
with water. Copper pipes led the heated water into the boiler.

There
have been differences in opinion on who should be given the credit for
designing Rocket. George Stephenson had designed several locomotives
before but none as advanced as Rocket. At the time that Rocket was being
designed and built at the Forth Banks Works, he was living in Liverpool
overseeing the building of the Liverpool and Manchester Railway. His
son Robert had recently returned from a stint working in South America
and resumed as managing director of Robert Stephenson and Company. He
was in daily charge of designing and constructing the new locomotive.
Although he was in frequent contact with his father in Liverpool and
probably received advice from him, it is difficult not to give the
majority of the credit for the design to Robert. A third person who
deserves a significant amount of credit is Henry Booth, the treasurer of
the Liverpool and Manchester Railway. He is believed to have suggested
to Robert Stephenson that a multi-tube boiler should be used.
The
opening ceremony of the L&MR, on 15 September 1830, was a
considerable event, drawing luminaries from the government and industry,
including the Prime Minister, the Duke of Wellington. The day started
with a procession of eight trains setting out from Liverpool. The parade
was led by Northumbrian driven by George Stephenson, and included
Phoenix driven by his son Robert, North Star driven by his brother
Robert Sr. and Rocket driven by assistant engineer Joseph Locke. The day
was marred by the death of William Huskisson, the Member of Parliament
for Liverpool, who was struck and killed by Rocket at Parkside.
In
1834, the engine was selected for modifications to test a
newly-developed rotary steam engine designed by Lord Dundonald. At a
cost of nearly £80, Rocket's cylinders and driving rods were removed and
two of the engines were installed directly on its driving axle with a
feedwater pump in between. On October 22, of that year, an operational
trial was held with disappointing results; one witness observing, that
"the engine could not be made to draw a train of empty carriages". Due
to inherent design flaws and engineering difficulties associated with
their design, Dundonald's engines were simply too feeble for the task.
