Some had wheels that flipped, but these had to be pushed or pulled. A few of the early 19th-century push toy trains were made of tinplate, like the big, durable, stylized locomotive toys in the U.S., which were painted gold and red and decorated with hearts and flowers. model train journal forum
Around 1875, technological improvements in materials and manufacturing enabled tin to be stamped, cut, rolled, and lithographed faster than ever before.
Toy trains were altered when Märklin, a German firm that specialized in doll house accessories, sought to make an equal toy for boys in which a constant revenue stream could be guaranteed by purchasing add-on accessories for years 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 buildings and scenery in addition to an operating train.
Electric trains followed, with the first appearing in 1897, made from the U.S. company Carlisle & Finch. As home use of power became more common in the early 20th century, electric trains gained popularity and as time moved on, these electric trains grew in sophistication, gaining light, the ability to change direction, to emit a whistling noise, to smoke, to couple and uncouple cars and even load and unload cargo. Toy trains from the first half of the 20th century were often made of lithographed tin; later trains were frequently made mostly of plastic.
Prior to 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 by 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.
Today, S gauge and O gauge railroads continue to be considered toy trains even 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 produced by Marx from the 1950s to the 1970s). However, due to their high price, one is more inclined to find an HO scale or N scale train set in a toy store than a O scale set.
Many modern electrical toy trains comprise sophisticated electronics which exude digitized sound effects and permit the operator to securely and easily run multiple remote controller trains on one loop of track. In recent years, many toy train operators may operate a train with a TV camera in the front of the engine and hooked up to a display, such as computer monitor. This will show a picture, like that of a real (smaller size) railroad.
