Track style
General railroad style (see "Type")
—
Passenger. Sets that replicate passenger trains - from city trains to high-speed express trains
—
Freight (commodity). Sets that replicate freight (goods) trains. They differ in variety: if on a passenger train the cars have the same design, then on a freight train there may be cars of different types.
-
Retro. Sets replicating vintage trains, often with steam locomotives as locomotives.
-
Children's. Railways designed for younger children. They are made in a characteristic bright design, are distinguished by their simplicity of design, and the tracks often have a specific structure: instead of rails, train wheels roll along furrows-ruts. This device simplifies the installation of “equipment” on the rails and minimizes the likelihood that it will go off the tracks.
Number of locomotives
The number of locomotives supplied with the railway (see "Type").
Many children's railways are equipped with just one locomotive, enough to run the train. However, there are also exceptions. So, there are quite a few "tyanitolkaev" trains that have
two locomotives, from both ends of the train; in such trains it is possible to switch from one locomotive to another by swapping "head" and "tail" and running the train in the opposite direction. Three locomotives in a set can mean either three separate trains or a regular train plus a "pull". And four locomotives usually correspond to two pushers.
It should be noted that mainly children's railways are equipped with several trains (see "Road style").
Number of carriages
The number of carriages provided for in the railway (see "Type").
The number of carriages is selected taking into account the scale and length of the railway, so that the train does not take up too much space on the tracks. In the most extensive sets, up to ten wagons can be provided. And some manufacturers provide the possibility, if desired, to purchase additional wagons to the existing set.
