Some had wheels which turned, but these had to be pulled or pushed. Some of the early 19th-century drive toy trains were made of tinplate, like the large, durable, stylized locomotive toys from the U.S., which were painted red and gold and decorated with hearts and flowers. model trains layouts ho
Around 1875, technological improvements in materials and manufacturing allowed tin to be scraped, cut, wrapped, and lithographed faster than previously.
Toy trains were revolutionized when Märklina German company which specialized in doll house accessories, sought to make an equal toy for boys in which a constant revenue stream could be guaranteed by purchasing add-on accessories for decades after the initial purchase. In addition to boxed sets containing a train and monitor, Märklin offered extra track, rolling stock, and buildings offered separately, creating the predecessor to the modern model train layout featuring scenery and buildings in addition to an operating train.
Electric trains followed, with the first appearing in 1897, produced from the U.S. company Carlisle & Finch. As home use of electricity became more prevalent in the early 20th century, electrical trains gained popularity and as time moved on, these electric trains grew in sophistication, gaining lighting, the ability to change direction, to emit a whistling sound, to smoke, to 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; afterwards trains were frequently made mostly of plastic.
Pull toys and wind-up trains were marketed towards children, while electrical trains were marketed towards teenagers, especially teenaged boys.
Today, S gauge and O gauge railroads are still considered toy trains even by their 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 from the 1950s to the 1970s). However, as a result of their high cost, one is more likely to locate an HO scale or N scale train set at a toy store than a O scale set.
Many modern electric toy trains contain sophisticated electronics which exude digitized sound effects and permit the operator to safely and easily run several remote control trains on one loop of track. In recent years, many toy rail operators may operate a train with a TV camera in the front of the motor and hooked up to a display, such as computer monitor. This will show a picture, like that of a real (smaller size) railroad.
