The earliest toy trains were made from lead and had no moving parts. Some had wheels which flipped, but these had to be pushed or pulled. A few of the early 19th-century push toy rails were made from tinplate, like the big, durable, stylized locomotive toys from the U.S., which were painted gold and red and decorated with hearts and flowers. model trains portland
Around 1875, technological improvements in materials and manufacturing enabled tin to be stamped, cut, wrapped, and lithographed faster than previously.
Toy trains were altered when Märklin, a German firm that specialized in doll house accessories, sought to make an equal toy for boys in which a constant revenue stream could be guaranteed by purchasing add-on accessories for decades 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 a working train.
Electric trains adopted, with the first appearing in 1897, produced by the U.S. company Carlisle & Finch. As residential use of electricity became more common from the early 20th century, electrical trains gained popularity and as time went on, these electrical trains grew in sophistication, gaining lighting, 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 from the first half of the 20th century were often made of lithographed tin; afterwards trains were often made mostly of plastic.
Before the 1950s, there was little distinction between toy trains and model railroads–model railroads were toys by definition. Pull toys and wind-up trains were marketed by children, while electric trains were marketed towards teenagers, particularly teenaged boys.
Today, S gauge and O gauge railroads are still considered toy trains by their adherents and are often accessorized with semi-scale model buildings by Plasticville or K-Line (who owns the rights to the Plasticville-like buildings created by Marx in the 1950s into the 1970s). However, due to 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 set.
Many modern electrical toy trains comprise sophisticated electronic equipment which emit digitized sound effects and allow the operator to securely and easily run several remote controller trains on a single loop of course. In recent years, many toy rail operators may operate a train using a TV camera in the front of the motor and hooked up to a screen, such as computer monitor. This will show an image, like that of a real (smaller size) railroad.
