Some had wheels which turned, but these needed to be pushed or pulled. Some of the early 19th-century push toy rails were made of tinplate, like the large, durable, stylized locomotive toys in the U.S., that were painted red and gold and decorated with hearts and flowers. trainz model railroad
Around 1875, technological advancements in materials and manufacturing enabled tin to be scraped, 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 continuous revenue stream could be ensured by purchasing add-on accessories for years after the initial purchase. Along with boxed sets containing 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 along with a working 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 prevalent from the early 20th century, electrical trains gained popularity and as time moved 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 and even load and unload cargo. Toy trains by the first half of the 20th century were frequently made of lithographed tin; afterwards trains were frequently made mostly of plastic.
Pull toys and wind-up trains were marketed towards children, while electric trains were marketed towards teenagers, especially teenaged boys. It was during the 1950s the modern emphasis on realism in model railroading started to catch on.
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 produced by Marx in the 1950s into the 1970s). However, as a result of their high price, one is more inclined to find an HO scale or N scale train set at a toy shop than an O scale collection.
Many modern electric toy trains comprise sophisticated electronic equipment which exude digitized sound effects and allow the operator to safely and easily run multiple remote controller trains on a single loop of track. In recent years, many toy train operators will operate a train with a TV camera in the front of the motor and hooked up to a screen, such as computer monitor. This will show a picture, like that of a genuine (smaller size) railroad.
