Final answer:
Theodore Judah did not establish a railroad museum in the Capitol as part of his efforts to secure subsidies for the building of a transcontinental railroad. The correct option is D. He established a railroad museum in the Capitol
Step-by-step explanation:
The efforts made by Theodore Judah to secure subsidies for the building of a transcontinental railroad excluded establishing a railroad museum in the Capitol.
Judah played a crucial role in the planning and lobbying for the First Transcontinental Railroad by volunteering his personal fortune, calling for a railroad convention to meet in San Francisco, spending two years lobbying Congress for federal support, and soliciting money from Oregon and Nevada.
However, there is no historical evidence suggesting he established a railroad museum in the Capitol as part of these efforts. The correct option is D. He established a railroad museum in the Capitol
