How many cars can fit on 7 track inside Harrison Yard?

The correct answer is ten, which aligns with the operational capacity of Harrison Yard's tracks. Each track in the yard is designed to accommodate a specific number of train cars based on standard practices and yard layout design. When evaluating the number of cars that can fit on multiple tracks, it is important to consider the length of each track and the types of cars being accommodated. In this case, if each of the seven tracks has a capacity that allows ten cars in total, that confirms the selection of the number ten as the answer. This capacity ensures efficient management of trains in the yard while adhering to operational safety standards.
