The first toy trains were made of lead and had no moving parts. Some had wheels that turned, but these needed to be pushed or pulled. A few of the early 19th-century drive toy rails were made of 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. transmodeler caliper
Around 1875, technological improvements in materials and manufacturing enabled tin to be stamped, cut, rolled, and lithographed faster than previously.
Toy trains were revolutionized when Märklina German firm which specialized in doll house accessories, sought to make an equal toy for boys where 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 additional track, rolling stock, and buildings offered separately, creating the predecessor to the modern model train layout featuring buildings and scenery in addition to an operating train.
Electric trains adopted, with the first appearing in 1897, made by the U.S. company Carlisle & Finch. As residential use of power became more common in the early 20th century, electric trains gained popularity and as time went on, these electrical trains grew in sophistication, gaining lighting, the ability to change direction, to emit a whistling sound, to smoke, to 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; later trains were often made mainly of plastic.
Pull toys and wind-up trains were marketed towards kids, while electric trains were marketed towards teens, especially 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.
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 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 locate an HO scale or N scale train set in a toy store than a O scale collection.
Many modern electrical toy trains contain sophisticated electronic equipment that emit digitized sound effects and allow the operator to securely and easily run several remote controller trains on one loop of track. In recent decades, many toy rail operators will operate a train using a TV camera in the front part of the engine and hooked up to a screen, such as computer monitor. This will show a picture, like that of a real (smaller size) railroad.
