The earliest toy trains were made from lead and had no moving parts. Some had wheels which turned, but these had to be pushed or pulled. A few of the early 19th-century drive toy rails were made of tinplate, like the large, durable, stylized locomotive toys in the U.S., that were painted red and gold and decorated with hearts and flowers. model trains virginia
Around 1875, technological improvements in materials and manufacturing allowed tin to be scraped, cut, rolled, and lithographed faster than ever before.
Toy trains were revolutionized when Märklin, a German company which specialized in doll house accessories, sought to make an equivalent toy for boys in which a continuous revenue stream could be ensured by selling 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 sold 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, produced from the U.S. company Carlisle & Finch. As residential use of power became more prevalent from the early 20th century, electrical trains gained popularity and as time moved on, these electric trains grew in sophistication, gaining lighting, the ability to change direction, to emit a whistling noise, to smoke, to couple and uncouple cars and even load and unload freight. Toy trains from the first half of the 20th century were often made of lithographed tin; later trains were often made mainly of plastic.
Pull toys and wind-up trains were marketed towards kids, while electric trains were marketed towards teenagers, particularly teenaged boys.
Now, S gauge and O gauge railroads continue to be considered toy trains 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 created by Marx in the 1950s into the 1970s). However, as a result of their high cost, one is more likely to locate an HO scale or N scale train set in a toy store than a O scale set.
Many modern electric toy trains contain sophisticated electronics that emit digitized sound effects and allow the operator to securely and easily run multiple remote control trains on one loop of course. In the last few years, many toy rail operators will operate a train using a TV camera in the front part of the motor and hooked up to a screen, such as computer monitor. This will show a picture, similar to that of a real (smaller size) railroad)
