In the material, which phrase is used to denote railroads where two or more lines of track are built on the same bank of earth?

• A. Railroads in juxtaposition
• B. Railroad in street
• C. Railroad siding
• D. Abandoned railroads

Answer: (A)

The main idea here is how to describe the arrangement of tracks that share the same earthen support. When two or more railroad lines run parallel on the same bank of earth, they’re described as being in juxtaposition—placed side by side on a common embankment. This term directly signals that the tracks are closely aligned and share the same raised bank, rather than being on separate foundations or in a street or side yard.

Other phrases point to different situations: one implies tracks laid within a street layout, another refers to a secondary track used for storage or siding off the main line, and the last describes tracks that are no longer in use. Those don’t capture the idea of multiple lines resting on a single bank the way juxtaposition does, so the described phrase best matches the scenario.
