The first toy trains were made of lead and had no moving parts. Some had wheels that flipped, but these had to be pulled or pushed. Some of the early 19th-century drive toy trains were made from 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 in allentown pa
Around 1875, technological advancements in materials and manufacturing allowed tin to be scraped, cut, wrapped, and lithographed faster than previously.
Toy trains were revolutionized when Märklin, a 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 purchasing add-on accessories for years after the first purchase. In addition to 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 an operating 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, electric 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 frequently made of lithographed tin; later trains were often made mostly of plastic.
Pull toys and wind-up trains were marketed towards kids, while electrical trains were marketed towards teenagers, especially teenaged boys.
Today, S gauge and O gauge railroads continue to be 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 in the 1950s into the 1970s). However, as a result of 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 collection.
Many modern electrical toy trains contain sophisticated electronics which exude digitized sound effects and allow the operator to securely and easily run several remote control trains on a single loop of track. In recent years, many toy train operators will operate a train using a TV camera at the front part of the motor and hooked up to a screen, such as computer monitor. This will show an image, like that of a genuine (smaller size) railroad)
