If railway track lines are kept parallel and equally spaced even in the distance, what weakness will occur?

The illusion of perspective and depth will weaken

The governing concept is linear perspective. In a real view, the two rails recede away from the viewer, so their apparent distance gradually decreases and their directions seem to move toward a vanishing point. If the artist keeps them parallel and equally spaced throughout the picture, this visual change is removed. The viewer then receives little evidence that the tracks travel into the distance, so the illusion of depth becomes weak or flat. Therefore, option A is correct. Option B is the opposite of what happens; the track will look less realistic. Option C is incorrect because parallel, equally spaced lines do not establish a convincing vanishing point. Option D concerns stroke thickness, not spatial recession.
