Some had wheels which turned, but these had to be pulled or pushed. A few of the early 19th-century push toy trains were made of tinplate, such as the large, durable, stylized locomotive toys in the U.S., that were painted gold and red and decorated with hearts and flowers. trains models and trolley car in ho gauge
Around 1875, technological improvements in materials and manufacturing enabled tin to be scraped, 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 in which a continuous revenue stream could be ensured by selling add-on accessories for years after the initial purchase. Along with boxed sets containing a train and track, 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 by the U.S. firm Carlisle & Finch. As home use of electricity became more common in the early 20th century, electrical trains gained popularity and as time moved on, these electric trains grew in sophistication, gaining light, 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 frequently made mostly of plastic.
Prior to 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 by children, while electric 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.
Now, 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 K-Line (who owns the rights to the Plasticville-like buildings created 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 in a toy shop than an O scale collection.
Many modern electric toy trains contain sophisticated electronics that exude 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 decades, many toy rail operators will operate a train with a TV camera in the front of the engine and hooked up to a display, such as computer monitor. This will show a picture, similar to that of a genuine (smaller size) railroad)
