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. A few of the early 19th-century push toy trains were made of tinplate, like the big, durable, stylized locomotive toys from the U.S., which were painted gold and red and decorated with hearts and flowers. train model custom houses brothers
Around 1875, technological improvements in materials and manufacturing enabled tin to be stamped, cut, wrapped, and lithographed faster than ever before.
Toy trains were altered when Märklin, a German company which specialized in doll house accessories, sought to make an equivalent toy for boys where a constant revenue stream could be guaranteed by purchasing add-on accessories for years after the initial purchase. Along with boxed sets containing a train and track, Märklin offered additional track, rolling stock, and buildings offered separately, creating the predecessor to the modern model train layout featuring buildings and scenery 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 from the early 20th century, electrical trains gained popularity and as time went on, these electric trains grew in sophistication, gaining light, the ability to change management, to emit a whistling noise, to smoke, to couple and uncouple cars as well as load and unload freight. Toy trains by the first half of the 20th century were often made of lithographed tin; later trains were frequently made mainly of plastic.
Pull toys and wind-up trains were marketed towards kids, while electrical trains were marketed towards teenagers, particularly 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 into the 1970s). However, as a result of their high cost, one is more likely to find an HO scale or N scale train set in a toy store than an O scale collection.
Many modern electric toy trains contain sophisticated electronics which emit digitized sound effects and permit the operator to safely and easily run multiple 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 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)
