Final Answer:
This statement is true.
Explanation:
The rapid proliferation of railroad lines in the 19th century did create an impression of economic growth, but this growth was often exaggerated. While railroads did significantly contribute to the expansion of industries, trade, and overall economic development, their rapid expansion also led to speculative investments and financial bubbles. In some cases, the construction of railroads outpaced the actual demand, leading to overbuilding and financial instability, particularly evident during events like the Panic of 1873. In actuality, this scenario was partially driven by speculative endeavors rather than strong economic foundations, creating the false impression of sustainable economic growth.
