Some had wheels that turned, but these needed to be pulled or pushed. Some of the early 19th-century drive toy trains were made of tinplate, like the big, durable, stylized locomotive toys from the U.S., that were painted gold and red and decorated with hearts and flowers. model trains forum
Around 1875, technological improvements in materials and manufacturing enabled tin to be stamped, cut, wrapped, and lithographed faster than previously.
Toy trains were revolutionized when Märklin, a German firm that 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 initial purchase. Along with 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 a working train.
Electric trains adopted, with the first appearing in 1897, produced by 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 went on, these electrical trains grew in sophistication, gaining lighting, the ability to change management, to emit a whistling noise, to smoke, to remotely couple and uncouple cars as well as load and unload cargo. Toy trains by the first half of the 20th century were often made of lithographed tin; afterwards trains were frequently made mainly of plastic.
Before the 1950s, there was little distinction between toy trains and model railroads–model railroads were toys by definition. Pull toys and wind-up trains were marketed towards children, while electrical trains were marketed towards teens, especially 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 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 in the 1950s into the 1970s). However, due to their high price, one is more likely to locate an HO scale or N scale train set at a toy shop than a O scale set.
Many modern electric toy trains comprise sophisticated electronics that emit digitized sound effects and allow the operator to safely and easily run multiple remote controller trains on one loop of course. In the last few years, many toy train operators may operate a train with a TV camera in the front part of the engine and hooked up to a screen, such as pc monitor. This will show an image, similar to that of a genuine (smaller size) railroad.
