Rail transport modelling

Rail transport modelling is when people build mini versions of trains and railways, that can be played with and move around.

First, you need to imagine that you are playing with toy trains, but instead of simply playing with them on the carpet or table, you build a little world for them to travel through. You can build mountains, cities, and other features, such as trees and rivers, and create detailed scenery for the trains to pass through.

These toy trains are called "model trains" and they come in a variety of sizes, ranging from tiny ones that can fit in the palm of your hand, to larger ones that are about as big as a regular toy car. You can buy them individually or in sets and there are many types of model trains, just like real trains, such as steam trains or modern diesel engines.

Building the railway can be tricky, but it's like putting together a big puzzle. You purchase small pieces of track, like a puzzle piece, and connect them together to create the railway. You can create hills, valleys, tunnels and bridges, and even buildings to go alongside the track.

Lastly, you can control the train with an electrical remote, which lets you control how fast the train goes and where it goes, like a video game controller.

Overall, rail transport modelling is a fun hobby that requires creativity, patience and imagination, where you can take control of your own little world and play with trains.
