The first toy trains were made from lead and had no moving parts. Some had wheels that turned, but these had to be pulled or pushed. A few of the early 19th-century push toy rails were made from tinplate, like the large, durable, stylized locomotive toys in the U.S., that were painted gold and red and decorated with hearts and flowers. trains model san diego toys youtube
Around 1875, technological advancements in materials and manufacturing enabled tin to be scraped, cut, wrapped, and lithographed faster than previously.
Toy trains were revolutionized when Märklin, a German company which specialized in doll house accessories, sought to make an equal toy for boys in which a constant revenue stream could be guaranteed by selling add-on accessories for years after the first purchase. In addition to boxed sets comprising a train and track, Märklin offered additional track, rolling stock, and buildings sold 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, produced from the U.S. company Carlisle & Finch. As home use of electricity became more common from the early 20th century, electric trains gained popularity and as time went on, these electrical trains grew in sophistication, gaining light, the ability to change direction, to emit a whistling sound, to smoke, to couple and uncouple cars as well as load and unload freight. Toy trains from the first half of the 20th century were frequently made of lithographed tin; afterwards trains were often 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 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 to the 1970s). However, due to their high price, one is more likely to find an HO scale or N scale train set in a toy shop than an O scale set.
Many modern electrical toy trains contain sophisticated electronic equipment that emit digitized sound effects and allow the operator to safely and easily run several remote controller trains on one loop of track. In recent years, many toy rail operators may operate a train using a TV camera at the front 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.
