History and development of Hornby model trains
Hornby are the UKs leading producers of and N gauge and 00 Gauge trains. Hornby have been producing model railway items since 1920 although it was 5 years until they produced their first electric train and not until 1938 just prior to the war that they created what is now the standard size train in the UK 00 gauge. During the war production ceased and but the development of Hornby trains as continued over the years with Locos and building becoming more and more detailed as production methods improved. Technology has also helped to add further realism to train sets with the introduction of Digital layouts which can program up to 99 trains for use with just one controller. All points and lights can be operated from one simple to operate system. Other features are lights can stay on even if the train is stationary, engine acceleration can be preset as to the deceleration, Speeds can be kept constant even when trains are climbing or descending in heights on multi levelled layouts, this helps keep trains running constant and on time. Even if this is not the case in the real world....
Further improvements to the 00 gauge trains are the introduction of Live Steam trains that create real steam from the trains. The live steam tracks do have to be operated from a separate controller and can be expensive to purchase in the first place but buyers will not be disappointed with the extra effect of the smoke on your layout. Other recent advances are the Sound locos, these Hornby trains are available as steam and diesel. Although the trains are digitally fitted they can be operated on the old style analogue layouts, not all features of the sound will work, the general speeding up and slowing down of the train remains correct when in operation on a analogue track.
Taking up Hornby trains as a hobby may not be cheap but with well built products and a wide range if items available there is so much to keep you entertained for many years. This is the principal that Hornby has made its success. With train sets being passed down by generations. There is no reason why this process will not continue in the future.

Related to traction pls.........?
In electric locomotive generally regenerative braking is used.
It is also a fact that we cannot use that energy generated out of that loc. If this is so then what is its reason?
And another q is Where we get out put of that braking i.e. power and how it is supplied to loco when it is generated?
Help me pls!!!
With regenerative braking, the traction motors act as generators. The control unit commands the motors to operate at a reduced speed and the inertia of the locomotive and its load produces a force that tries to maintain the speed of the motor. That force is used to drive the motor as a generator and generate electric energy. The motor acting as a generator represents a load on the locomotive and produces a braking force.
The energy generated by regenerative braking can be stored and reused by the locomotive if the locomotive is equipped with energy storage devices such as batteries. The batteries would need to be capable of accepting a lot of charging energy in a relatively short time. A charging control unit would need to be supplied. Some of the energy would be lost because the charging process is not 100% efficient. Storing the energy on the locomotive is not generally considered to be cost effective. In most cases, the braking energy is returned to the supply system where it can be used by other locomotives.
