The first toy trains were made from lead and had no moving parts. Some had wheels that turned, but these needed to be pushed or pulled. Some of the early 19th-century drive toy rails were made of tinplate, like the large, durable, stylized locomotive toys in the U.S., which were painted red and gold and decorated with hearts and flowers. trains model trains
Around 1875, technological advancements in materials and manufacturing allowed tin to be stamped, cut, wrapped, and lithographed faster than ever before.
Toy trains were revolutionized when Märklina German firm that specialized in doll house accessories, sought to make an equal 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 containing a train and monitor, Märklin offered extra track, rolling stock, and buildings sold separately, creating the predecessor to the modern model train layout featuring scenery and buildings in addition to a working train.
Electric trains followed, with the first appearing in 1897, produced by the U.S. company Carlisle & Finch. As residential use of power became more prevalent from the early 20th century, electrical trains gained popularity and as time went on, these electrical trains grew in sophistication, gaining light, the ability to change direction, to emit a whistling sound, to smoke, to couple and uncouple cars as well as load and unload cargo. Toy trains from 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 teenagers, particularly teenaged boys. It was during the 1950s the modern emphasis on realism in model railroading started to catch on.
Today, 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 K-Line (who owns the rights to the Plasticville-like buildings produced by Marx in the 1950s into the 1970s). However, due to their high cost, one is more likely 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 electronics which exude digitized sound effects and allow the operator to safely and easily run several remote controller trains on a single loop of course. In the last few decades, many toy rail operators may 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.
