The right answer is Lincoln signed the Pacific Railroad Act of 1862 into law, which stimulated the construction of the railroad.

Here is a brief explanation:

Authorization for the construction of the railroad came through the Railroad Act of the Pacific, which occurred in the year 1862 with the support of the United States government. But for many decades, there was already a movement that called for the early development of the railroad. The beginning of the works was the end result of the attitudes of the time Abraham Lincoln presided over the U.S., but the project was only completed after his death.
