Basis of the private financial system
Railroads financing provided the basis for a dramatic expansion of the private (non-governmental) financial system. Construction of railroads was far more expensive than factories. In 1860, the combined total of railroad stocks and bonds was $1.8 billion; 1897 it reached $10.6 billion (compared to a total national debt of $1.2 billion).[26] Funding came from financiers throughout the Northeast, and from Europe, especially Britain.[27] About 10 percent of the funding came from the government, especially in the form of land grants that could be realized when a certain amount of trackage was opened.[28] The emerging American financial system was based on railroad bonds. New York by 1860 was the dominant financial market. The British invested heavily in railroads around the world, but nowhere more so than the United States; The total came to about $3 billion by 1914. In 1914–1917, they liquidated their American assets to pay for war supplies.[29][30]
