Railroadiana or railwayana refers to artifacts of currently or formerly operating railways around the world.

Railroadiana/railwayana can include items such as:^[1]

• Railway books and magazines
• Model railway locomotives, rolling stock and equipment

There are many more types of railroadiana available to the collector. Some railroadiana collectors include items in their collections as large as speeders or complete passenger cars.^{[citation needed]}

The majority of pieces forming a collection can be legally obtained, often but not always at low cost, from either surplus or scrap sales from the railroad companies themselves, or through aftermarket railroadiana shows. Highly desirable items (rare or from popular lines) may sell for significant multiples of their original price.^{[citation needed]}
