The first toy trains were made from lead and had no moving parts. Some had wheels that turned, but these had to be pushed or pulled. Some of the early 19th-century drive toy rails were made from tinplate, like the large, durable, stylized locomotive toys from the U.S., which were painted gold and red and decorated with hearts and flowers. model trains tunnel
Around 1875, technological advancements in materials and manufacturing allowed tin to be stamped, 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 constant revenue stream could be guaranteed by selling add-on accessories for decades after the initial 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 scenery and buildings along with an operating train.
Electric trains adopted, with the first appearing in 1897, produced from the U.S. firm Carlisle & Finch. As home use of electricity became more common from the early 20th century, electric trains gained popularity and as time moved on, these electrical trains grew in sophistication, gaining light, the ability to change management, to emit a whistling noise, to smoke, to remotely couple and uncouple cars and even load and unload cargo. Toy trains by the first half of the 20th century were often made of lithographed tin; afterwards trains were often made mainly of plastic.
Before the 1950s, there was little differentiation between toy trains and model railroads–model railroads were toys by definition. Pull toys and wind-up trains were marketed towards kids, while electrical trains were marketed towards teens, particularly teenaged boys.
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 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, due to their high price, one is more inclined to find an HO scale or N scale train set at a toy store than a O scale collection.
Many modern electric toy trains comprise sophisticated electronics that emit digitized sound effects and permit the operator to securely and easily run multiple remote controller trains on one loop of track. In the last few decades, many toy train operators may operate a train using a TV camera in the front part of the motor and hooked up to a display, such as pc monitor. This will show a picture, similar to that of a genuine (smaller size) railroad.
