Some had wheels which turned, but these had to be pulled or pushed. A few of the early 19th-century drive toy rails were made from tinplate, such as the large, durable, stylized locomotive toys in the U.S., which were painted red and gold and decorated with hearts and flowers. transmodeler multiple demand matrices
Around 1875, technological advancements in materials and manufacturing enabled tin to be scraped, cut, wrapped, and lithographed faster than previously.
Toy trains were revolutionized when Märklin, a German firm which specialized in doll house accessories, sought to make an equivalent toy for boys in which a constant revenue stream could be ensured by purchasing add-on accessories for years after the initial purchase. In addition to boxed sets comprising a train and monitor, Märklin offered additional track, rolling stock, and buildings sold separately, creating the predecessor to the modern model train layout featuring buildings and scenery along with an operating train.
Electric trains adopted, with the first appearing in 1897, made from the U.S. firm Carlisle & Finch. As residential use of electricity became more common in the early 20th century, electrical trains gained popularity and as time moved on, these electrical trains grew in sophistication, gaining lighting, the ability to change management, to emit a whistling noise, 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 often made of lithographed tin; afterwards trains were often made mostly of plastic.
Pull toys and wind-up trains were marketed towards kids, while electric trains were marketed towards teens, especially teenaged boys. It was during the 1950s that the modern emphasis on realism in model railroading began to grab on.
Today, S gauge and O gauge railroads continue to be considered toy trains even 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 to the 1970s). However, as a result of their high cost, one is more likely to find an HO scale or N scale train set in a toy store than a O scale set.
Many modern electrical toy trains contain sophisticated electronic equipment that exude digitized sound effects and permit the operator to safely and easily run several remote control trains on a single loop of track. In the last few decades, many toy rail operators will operate a train with 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)
