									                         Model Trains for Beginners

                             The majority of model trains run on
electricity, generally operated on a low-voltage DC supply system while
other companies are choosing to use an AC supply system. In the day,
electric model trains ran on batteries because electricity wasn't near as
widespread, as seen today. These kinds of trains are rather inexpensive
and not idyllic for train model enthusiasts.

     Electric Train Models Of The Past and Present

      Train models of the yester-years used a three-rail system with
wheels that ran on a metal track amid metal sleepers that would conduct
the power. This was highly convenient since the majority of model trains
were constructed of metal along with the track and rolling stocks.
However, as models became more accurate, a two-rail system was created;
the wheels became isolated and the tracks carried a positive and negative
supply (or two sides of an AC supply system). This system allowed for
fine metal studs rather than a central rail, which gave it a more
realistic look.

      The early types used steam or clockwork that would make it run
until it had no juice left; there was no way a person could control how
fast or slow it was going and no way to stop or start it. However,
electric model trains allowed for more sophistication including train
throttles. The AC powered locomotives had mechanisms that would allow
users to change direction and control the speed. DC powered locomotives
allowed users to change directions by reversing the polarity. Trains
could be stopped by removing/shutting down blocks from the track layout.
The controller would be able to run more than one train and control the
speed of every one; plus the controller would have control over the other
accessories that would make the models real.

     A Look At Two Popular Electric Train Models

      Now the majority of them are electric but the more popular models
are the N and 0 scale types.

      N Scale Models - Most train enthusiasts favor the N scale models,
which have scales that range 1:148 to 1:160 with a gauge of nine
millimeters. One reason it's favored is the scale because it's half the
size of the H0 scale and allows enthusiasts to create layouts that are
small but very detailed. While there are smaller train models, they don't
match the popularity seen with the N scale model, which are powered by DC
12-volt capacity.

      The DC voltage that's given to the rails will determine the train's
speed and direction. New N scale train model versions use a DCC system
that sends out train control signals through a decoder, which are
installed in every locomotive. This gives the user more control over the
train's speed and direction than what the AC and DC could provide.
      0 Scale Model Trains - These electric model trains are very popular
for model railroading and toy trains. They are popular for three big
reasons:

      - Durability
- Price
- Easy to handle and work by children

      Modelers often prefer the 0 scale type. These trains run on both
the three-rail system from the early 1930s to the late 1960s; however,
decline for them came with the introduction of the smaller models and a
low-voltage DC supply was provided. It gets his name for the zero-gauge
due to its small scale of other model trains before World War II, with
ranges of 1:48 to 1:64; however, the Marklin Company had asked for
specifications of 1:43. These trains are clearly more for collectibles
and train running enthusiasts.
