Some had wheels which turned, but these needed to be pushed or pulled. Some of the early 19th-century drive toy trains were made of tinplate, such as the large, durable, stylized locomotive toys from the U.S., which were painted red and gold and decorated with hearts and flowers. model trains worth money
Around 1875, technological advancements in materials and manufacturing allowed tin to be stamped, cut, rolled, and lithographed faster than previously.
Toy trains were altered when Märklin, a German company 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 decades after the initial purchase. Along with boxed sets comprising a train and track, 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 a working train.
Electric trains followed, with the first appearing in 1897, produced by the U.S. firm Carlisle & Finch. As home use of power became more prevalent in the early 20th century, electrical trains gained popularity and as time went on, these electric 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 cargo. 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 by kids, while electric trains were marketed towards teens, particularly teenaged boys.
Consumer interest in trains as toys waned in the late 1950s, but has experienced 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 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 cost, one is more inclined to locate an HO scale or N scale train set in a toy shop than an O scale collection.
Many modern electrical toy trains contain sophisticated electronic equipment which exude digitized sound effects and allow the operator to securely and easily run several remote control trains on a single loop of course. 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, similar to that of a real (smaller size) railroad.
