This section explains the available scales in hobby trains and what options are readily available in India

About Scale and Power requirements

There is a recognized-standard scale applied in many countries. Scale is a needed-parameter, so that selected model can be combined to other models from different manufacturers. Appropriate train and track scale can also create a diorama layout, which can be complemented to the model train display and atmosphere with balance composition.

There are atleast five scales often used by model railway enthusiasts. They are:

1. G Scale

G scale train is the largest commercial hobby scale and is typically used in gardens, hence the designation "G." It is 1:22.5, which means the real prototype is 22.5 times larger than the model.

2. O Scale

O scale is 1:48 scale. If you divided the length in inches of a real boxcar or engine by 48 you would have the length of an O-scale model. The oldest O-scale trains run on three rail tracks.

3. HO Scale (popular)

HO scale trains is derived from the fact that is is approximately half O scale at 1:87. It is the most popular scale in the world for serious modelers. An HO-scale model is 1/87th the length, height and width of the real thing.

4. N Scale (popular)

N scale trains is 1:160 in its proportions. It would take 160 models to equal the length of the real-world objects they represent. N scale is now nearly as popular as HO because it is highly detailed and uses smaller models, allowing for more train in less space.

5. Z Scale

Developed in Europe where interior space is at a premium, Z scale is 1:220 scale. Engines and boxcars are often less than an inch long, and working layouts can even be done in the space of a suitcase.

Power and control

Power and control for model train can be shared into three types: AC, DC and DCC. This tutorial will only cover DC and DCC because they are the most widely used system by hobbyist. DC (Direct Current)

How it works? A part of system is electrified with 0V, but another one is + Volt. To accelerate the speed of train, we can add more voltage on the + volts.

Benefits: Easy and simple. Controller for DC is also cheaper than DCC.

Disadvantages: Only one train can accommodate on railroad layout. If there are two trains in one layout, their speed cannot be independently regulated.

This problem can be overcome by separation creating a layout within a layout (voltage seperation). But model train application is complex and a DCC layout can easy the complixity.

Another disadvantage of DC is, accessories like lights on a locomotive will dim or glow bright depending on the voltage applied (higher the loco spead brighter the light).

DCC (Digital Command Control)

A scheme for controlling locomotives on a model railroad layout. It allows more than one locomotive to occupy the same electrical section of track. It allows for multiple operators to control multiple locomotives simultaneously, even in the same block (electrical division), which in analog (or DC power) is difficult at best, if not impossible.

If you only have the single DCC equipped locomotive that came with your starter set, you can run a single non-DCC (analog) locomotive along with your DCC locomotives.
