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. Some of the early 19th-century push toy trains were made of tinplate, like the big, durable, stylized locomotive toys in the U.S., that were painted gold and red and decorated with hearts and flowers. model trains wagga
Around 1875, technological advancements in materials and manufacturing allowed tin to be scraped, cut, wrapped, and lithographed faster than previously.
Toy trains were altered when Märklin, a German company which specialized in doll house accessories, sought to make an equal toy for boys where a constant revenue stream could be ensured by purchasing add-on accessories for decades after the initial purchase. Along with boxed sets containing a train and monitor, 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 followed, with the first appearing in 1897, made by the U.S. firm Carlisle & Finch. As home use of power became more common from 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 direction, to emit a whistling sound, 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; afterwards trains were frequently made mainly of plastic.
Pull toys and wind-up trains were marketed towards children, while electrical trains were marketed towards teens, especially teenaged boys. It was during the 1950s that the modern emphasis on realism in model railroading began to catch 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.
Now, S gauge and O gauge railroads continue to be 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 in the 1950s to the 1970s). However, as a result of their high price, one is more likely to find an HO scale or N scale train set at a toy store than a O scale set.
Many modern electric toy trains comprise sophisticated electronic equipment that exude digitized sound effects and allow the operator to securely and easily run multiple remote controller trains on one loop of track. In the last few years, many toy train operators will operate a train using a TV camera in the front of the motor and hooked up to a screen, such as pc monitor. This will show an image, similar to that of a real (smaller size) railroad)
