Some had wheels which flipped, but these needed to be pulled or pushed. Some of the early 19th-century push toy trains were made of tinplate, like the big, durable, stylized locomotive toys from the U.S., which were painted gold and red and decorated with hearts and flowers. model trains manufacturers
Around 1875, technological improvements in materials and manufacturing allowed tin to be scraped, cut, rolled, and lithographed faster than previously.
Toy trains were altered when Märklin, a German firm which specialized in doll house accessories, sought to make an equal toy for boys where a constant revenue stream could be guaranteed by selling add-on accessories for decades after the first purchase. In addition to boxed sets containing a train and track, Märklin offered extra track, rolling stock, and buildings offered separately, creating the predecessor to the modern model train layout featuring scenery and buildings along with a working train.
Electric trains followed, with the first appearing in 1897, made by the U.S. firm Carlisle & Finch. As home use of power became more common in the early 20th century, electrical trains gained popularity and as time went on, these electric trains grew in sophistication, gaining light, the ability to change management, to emit a whistling sound, to smoke, to 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; afterwards trains were frequently made mainly of plastic.
Pull toys and wind-up trains were marketed towards children, while electrical trains were marketed towards teens, particularly teenaged boys. It was during the 1950s the modern emphasis on realism in model railroading began to grab on.
Consumer interest in trains as toys waned in the late 1950s, but has experienced resurgence since the late 1990s due in large part to the popularity of Thomas the Tank Engine.
Now, 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 K-Line (who owns the rights to the Plasticville-like buildings produced by Marx from the 1950s into the 1970s). However, as a result of their high price, one is more likely to locate an HO scale or N scale train set in a toy shop than an O scale collection.
Many modern electric toy trains contain sophisticated electronics which emit digitized sound effects and allow the operator to securely and easily run multiple remote control trains on one loop of course. In recent decades, many toy train operators may operate a train with a TV camera at 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)
