The first 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 push toy trains were made from tinplate, such as the large, durable, stylized locomotive toys in the U.S., that were painted gold and red and decorated with hearts and flowers. model trains indianapolis
Around 1875, technological advancements in materials and manufacturing enabled tin to be stamped, cut, rolled, and lithographed faster than previously.
Toy trains were altered when Märklina German firm which specialized in doll house accessories, sought to make an equal toy for boys in which a constant revenue stream could be ensured by purchasing add-on accessories for years after the initial purchase. Along with 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 buildings and scenery in addition to a working train.
Electric trains adopted, with the first appearing in 1897, produced from the U.S. company Carlisle & Finch. As residential use of power became more common from the early 20th century, electric trains gained popularity and as time moved on, these electrical trains grew in sophistication, gaining light, the ability to change management, to emit a whistling sound, to smoke, to couple and uncouple cars as well as load and unload cargo. Toy trains by the first half of the 20th century were often made of lithographed tin; afterwards trains were often made mostly of plastic.
Pull toys and wind-up trains were marketed towards children, while electric trains were marketed towards teens, particularly teenaged boys.
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.
Now, 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 K-Line (who owns the rights to the Plasticville-like buildings produced by Marx in the 1950s to the 1970s). However, due to their high price, one is more inclined to find an HO scale or N scale train set at a toy shop than a O scale set.
Many modern electrical toy trains contain sophisticated electronics that exude digitized sound effects and allow the operator to securely and easily run several remote controller trains on a single loop of track. In recent decades, many toy rail operators will operate a train using a TV camera in the front of the engine and hooked up to a screen, such as pc monitor. This will show a picture, similar to that of a genuine (smaller size) railroad.
