The earliest toy trains were made of lead and had no moving parts. Some had wheels that flipped, but these needed to be pushed or pulled. Some of the early 19th-century push toy rails were made from tinplate, such as the big, durable, stylized locomotive toys in the U.S., which were painted red and gold and decorated with hearts and flowers. train model sets
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 which specialized in doll house accessories, sought to create an equivalent toy for boys in which a constant 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 additional track, rolling stock, and buildings sold separately, creating the predecessor to the modern model train layout featuring buildings and scenery in addition to a working train.
Electric trains followed, with the first appearing in 1897, made by the U.S. firm Carlisle & Finch. As residential use of power became more prevalent from the early 20th century, electric trains gained popularity and as time moved on, these electric 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 cargo. Toy trains by the first half of the 20th century were frequently 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 teens, especially teenaged boys. It was during the 1950s that the modern emphasis on realism in model railroading started to grab on.
Consumer interest in trains as toys waned in the late 1950s, but has experienced resurgence since the late 1990s due in large part to the popularity of Thomas the Tank Engine.
Today, S gauge and O gauge railroads are still considered toy trains by their own 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 from the 1950s to 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 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 train operators may operate a train using a TV camera at the front of the motor and hooked up to a display, such as computer monitor. This will show a picture, similar to that of a genuine (smaller size) railroad)
