| Description |
The CP 29 is an A-1-e class locomotive. It is equipped with 17 x 24-inch cylinders and 70-inch driving wheels. Its useable
tractive effort is 13,000 lbs. The 4-4-0 arrangement is the result of the first trials conducted in 1837, using a steering
truck in front. The four-wheeled truck made it easier to negotiate turns and maintain higher speeds. The other two, larger,
carrying wheels were connected to the pistons with expansion slide valves. Not long thereafter, with the introduction of larger
boilers, a support axle was added behind the locomotive, ending up with the 4-4-2 "Atlantic" type. The 4-4-0 arrangement was
so typical of North American railways that it was termed the "American" arrangement in the Whyte classification system. The
power and wheel layout of this type of locomotive meant that it could be used for both freight and passenger service.
|
| Narrative |
These locomotives, widely replaced by 4-6-0 "Ten Wheeler" types around 1900, continued in use on branch lines until the early
1960s.
|
| History of Use |
To haul passenger train. |
| Operating Principle |
The principle of the steam engine is that it transforms the heat energy of steam into mechanical energy, through expansion
and cooling of steam in a cylinder with a moving piston. The steam to produce the energy or heat is provided by a boiler,
fed with wood, coal or, later, heating oil. Combustion in the boiler emits steam, which collects under pressure in a steam
dome. The steam passes through a superheater consisting of tubes exposed to the hot gases, further increasing its temperature,
and is then sent to the pistons. When it returns, it is discharged into the smokestack through the smokebox. The movement
of the piston is the perfect example of how heat energy is transformed into linear mechanical energy, driving the locomotive.
A system of cranks and connecting rods transforms the back-and-forth motion of the piston into circular motion, causing the
wheels to turn.
