The earliest toy trains were made from lead and had no moving parts. Some had wheels which flipped, but these had to be pushed or pulled. Some of the early 19th-century drive toy rails were made from tinplate, such as the big, durable, stylized locomotive toys from the U.S., that were painted gold and red and decorated with hearts and flowers. model trains toy
Around 1875, technological advancements in materials and manufacturing allowed tin to be stamped, cut, wrapped, and lithographed faster than previously.
Toy trains were altered when Märklina German company which specialized in doll house accessories, sought to make an equal toy for boys where a continuous revenue stream could be guaranteed by selling add-on accessories for years after the initial purchase. Along with boxed sets comprising a train and track, Märklin offered extra track, rolling stock, and buildings sold separately, creating the predecessor to the modern model train layout featuring scenery and buildings in addition to a working train.
Electric trains adopted, with the first appearing in 1897, made from the U.S. firm Carlisle & Finch. As home use of electricity became more prevalent from the early 20th century, electric trains gained popularity and as time moved on, these electrical trains grew in sophistication, gaining lighting, the ability to change direction, to emit a whistling sound, to smoke, to remotely couple and uncouple cars as well as load and unload freight. Toy trains from the first half of the 20th century were frequently made of lithographed tin; later trains were frequently made mostly of plastic.
Pull toys and wind-up trains were marketed by children, while electrical trains were marketed towards teens, especially teenaged boys. It was during the 1950s the modern emphasis on realism in model railroading began to grab on.
Now, S gauge and O gauge railroads continue to be considered toy trains even by their adherents and are often accessorized with semi-scale model buildings by Plasticville or K-Line (who owns the rights to the Plasticville-like buildings produced by Marx in the 1950s to the 1970s). However, as a result of their high price, one is more likely to locate an HO scale or N scale train set in a toy shop than a O scale collection.
Many modern electric toy trains contain sophisticated electronic equipment which emit digitized sound effects and allow the operator to safely and easily run multiple remote control trains on one loop of track. In recent decades, many toy rail operators may operate a train with a TV camera in the front of the engine and hooked up to a screen, such as pc monitor. This will show a picture, like that of a genuine (smaller size) railroad.
