The earliest toy trains were made from lead and had no moving parts. Some had wheels that flipped, but these needed to be pulled or pushed. Some of the early 19th-century push toy trains were made from tinplate, such as the large, durable, stylized locomotive toys in the U.S., that were painted red and gold and decorated with hearts and flowers. model trains metra
Around 1875, technological improvements in materials and manufacturing enabled tin to be scraped, cut, wrapped, and lithographed faster than previously.
Toy trains were revolutionized when Märklina German firm which specialized in doll house accessories, sought to make an equivalent toy for boys in which a constant revenue stream could be guaranteed by selling add-on accessories for years after the initial purchase. In addition to boxed sets comprising a train and track, Märklin offered additional 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, produced from the U.S. company Carlisle & Finch. As home use of power became more common in the early 20th century, electrical trains gained popularity and as time went on, these electrical 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 often made of lithographed tin; afterwards trains were frequently made mainly of plastic.
Pull toys and wind-up trains were marketed towards kids, while electric trains were marketed towards teens, especially teenaged boys. It was during the 1950s that the modern emphasis on realism in model railroading started to catch on. Consumer interest in trains as toys waned in the late 1950s, but has undergone resurgence since the late 1990s due in large part to the popularity of Thomas the Tank Engine.
Today, S gauge and O gauge railroads continue to be considered toy trains 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 from the 1950s into 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 store than an O scale set.
Many modern electric toy trains contain sophisticated electronic equipment that exude digitized sound effects and allow the operator to securely and easily run multiple remote control trains on one loop of course. In recent decades, many toy rail operators will operate a train with a TV camera in the front part of the motor and hooked up to a display, such as computer monitor. This will show an image, similar to that of a genuine (smaller size) railroad)
