The earliest toy trains were made of lead and had no moving parts. Some had wheels which turned, but these had to be pulled or pushed. A few of the early 19th-century push toy rails were made of tinplate, such as the big, durable, stylized locomotive toys from the U.S., that were painted gold and red and decorated with hearts and flowers. model trains in india
Around 1875, technological improvements 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 that specialized in doll house accessories, sought to make an equal toy for boys in which a continuous revenue stream could be guaranteed by purchasing add-on accessories for years after the first purchase. In addition to boxed sets comprising 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 along with an operating train.
Electric trains adopted, with the first appearing in 1897, made from the U.S. company Carlisle & Finch. As home use of power became more prevalent in the early 20th century, electric trains gained popularity and as time went on, these electric trains grew in sophistication, gaining lighting, the ability to change management, to emit a whistling noise, to smoke, to remotely couple and uncouple cars and even load and unload freight. Toy trains from the first half of the 20th century were often made of lithographed tin; later trains were often made mostly of plastic.
Before 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 towards children, while electrical trains were marketed towards teenagers, particularly teenaged boys. It was during the 1950s the modern emphasis on realism in model railroading began to grab on.
Today, S gauge and O gauge railroads are still 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 created by Marx in the 1950s into the 1970s). However, as a result of their high cost, one is more inclined to find an HO scale or N scale train set in a toy shop than a O scale set.
Many modern electrical toy trains contain sophisticated electronics which emit digitized sound effects and allow the operator to safely and easily run multiple remote control trains on one loop of course. In the last few decades, many toy rail operators may 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, similar to that of a real (smaller size) railroad)
