This is a metal bridge that was made in the USA. I can’t find a maker’s mark on it. I would think Lionel and Marx would have their name on anything they produced. Anyhow, it can fit an O scale car or even a Standard Guage train. Pls see the pictures for that sizing. It’s about 12 inches long. (Rock Island). Observation Car is not included – just using it to show the size and width on the bridge.You will like this puppy! Will look good on your display or layout! A great collector piece!
