The earliest toy trains were made of lead and had no moving parts. Some had wheels which flipped, but these needed to be pushed or pulled. Some of the early 19th-century drive toy rails were made of tinplate, such as the large, durable, stylized locomotive toys in the U.S., which were painted gold and red and decorated with hearts and flowers. model trains museum
Around 1875, technological advancements in materials and manufacturing allowed tin to be stamped, cut, wrapped, and lithographed faster than previously.
Toy trains were altered when Märklina German company that specialized in doll house accessories, sought to create an equal toy for boys where a continuous revenue stream could be ensured by selling add-on accessories for years 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 buildings and scenery along with a working train.
Electric trains adopted, with the first appearing in 1897, made from the U.S. firm Carlisle & Finch. As home use of power became more common 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 management, to emit a whistling noise, to smoke, to remotely couple and uncouple cars as well as load and unload freight. Toy trains by the first half of the 20th century were frequently made of lithographed tin; afterwards trains were frequently made mainly of plastic.
Pull toys and wind-up trains were marketed by kids, while electric trains were marketed towards teens, especially teenaged boys.
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 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 cost, 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 electrical toy trains comprise sophisticated electronics which exude digitized sound effects and permit the operator to securely and easily run multiple remote controller trains on a single loop of course. In the last few years, many toy train operators may operate a train with a TV camera at 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)
