Example Input: Question: Who was wealthier when the Deepwater Railway was being built, Page or Rogers? Passage:Early in the 20th century, William Nelson Page, a civil engineer and coal mining manager, joined forces with a silent partner, industrialist financier Henry Huttleston Rogers (a principal of Standard Oil and one of the wealthiest men in the world), to develop the Deepwater Railway, a modest 85-mile long short line railroad to access untapped bituminous coal reserves in some of the most rugged sections of southern West Virginia. When Page was blocked by collusion of the bigger railroads, who refused to grant reasonable rates to interchange the coal traffic, he did not quit. As he continued building the original project, to provide their own link, using Rogers' resources and attorneys they quietly incorporated another intrastate railroad in Virginia, the Tidewater Railway. In this name, they secured the right-of-way needed all the way across Virginia to reach Hampton Roads, where a new coal pier was erected at Sewell's Point.
