Some had wheels that flipped, but these needed to be pushed or pulled. A few of the early 19th-century drive toy trains were made from tinplate, like the big, durable, stylized locomotive toys in the U.S., that were painted gold and red and decorated with hearts and flowers. train model lights
Around 1875, technological improvements in materials and manufacturing allowed tin to be stamped, cut, wrapped, and lithographed faster than ever before.
Toy trains were altered when Märklina German firm that specialized in doll house accessories, sought to make an equal toy for boys where a constant revenue stream could be ensured by selling add-on accessories for decades after the first purchase. Along with 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 scenery and buildings along with a working train.
Electric trains adopted, with the first appearing in 1897, made from the U.S. firm Carlisle & Finch. As home use of electricity became more prevalent in the early 20th century, electrical trains gained popularity and as time went on, these electrical trains grew in sophistication, gaining light, the ability to change direction, to emit a whistling sound, to smoke, to remotely couple and uncouple cars and even load and unload cargo. Toy trains from the first half of the 20th century were frequently made of lithographed tin; later trains were often made mainly of plastic.
Prior to 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 by kids, while electrical trains were marketed towards teens, particularly teenaged boys.
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 cost, one is more inclined to find an HO scale or N scale train set in a toy store than an O scale set.
Many modern electrical toy trains contain sophisticated electronic equipment which emit digitized sound effects and allow the operator to securely and easily run several 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 at the front 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.
