The earliest toy trains were made from lead and had no moving parts. Some had wheels which flipped, but these had to be pulled or pushed. Some of the early 19th-century push toy trains 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 korea
Around 1875, technological advancements in materials and manufacturing allowed tin to be scraped, cut, wrapped, and lithographed faster than previously.
Toy trains were altered when Märklina German firm which specialized in doll house accessories, sought to create an equivalent toy for boys in which a continuous revenue stream could be ensured by purchasing add-on accessories for years after the initial purchase. In addition to 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 buildings and scenery in addition to an operating train.
Electric trains adopted, with the first appearing in 1897, made by the U.S. company Carlisle & Finch. As residential use of electricity became more prevalent in the early 20th century, electrical trains gained popularity and as time moved on, these electrical trains grew in sophistication, gaining light, the ability to change direction, to emit a whistling noise, 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 teenagers, especially teenaged boys. It was during the 1950s the modern emphasis on realism in model railroading started to catch on.
Today, S gauge and O gauge railroads are still considered toy trains even by their own adherents and are often accessorized with semi-scale model buildings by Plasticville or even K-Line (who owns the rights to the Plasticville-like buildings produced by Marx in the 1950s into the 1970s). However, as a result of their high price, one is more inclined to find an HO scale or N scale train set in a toy store than an O scale collection.
Many modern electric toy trains comprise sophisticated electronic equipment that exude digitized sound effects and allow the operator to safely and easily run multiple remote controller trains on one loop of course. In recent years, many toy train operators may operate a train with a TV camera in the front part of the motor and hooked up to a screen, such as pc monitor. This will show an image, like that of a genuine (smaller size) railroad.
