G scale model trains refer to the type of model trains that can run on a G scale track. This type of train is often used in gardens or outdoors which is why the letter "G" is often misinterpreted to mean "garden". However, the letter "G" is short for the German word groß which literally means "big". The reason why G scale model trains are mostly found in the garden or outdoors is because of their durability. G scale tracks are usually made of brass which only requires almost no maintenance from the owner. A single wipe of clean cloth and it's set for operations once again. The G scale model trains on the other hand could be used for indoor or outdoor depending on the make up of the model train.

The benefit of a G scale model train is quite obvious: because of its durability, parents could be assured that their kids would have this toy for many years to come. Its size is also considerably larger compared to other trains: G scale model trains are usually 1:22 to the actually size while others could come be lower. G Scale Model Railroads are a great hobby for parents and children to enjoy.
