Within a few months came another change of proprietorship, the route passing on a mortgage foreclosure into the hands of Benjamin Holladay, a famous stage line promoter, late in 1861. Early the following year Holladay reorganized the management under the name of the Overland Stage Line. This seems to have been what today is technically known as a holding company; for until the expiration of the old Butterfield contract in 1863[[38]], he allowed the business east of Salt Lake City to be carried on by the old C. O. C. & P. P. Co.; west of Salt Lake, the new Overland Line allowed, or sublet the through traffic to a vigorous subsidiary, the Pioneer Stage Line[[39]].

Holladay was fortunate in securing a new mail contract for the Central route which he now controlled. For supplying a six day letter mail service from the Missouri to Placerville together with a way mail to and from Denver and Salt Lake City, he was paid $1,000,000 a year for the three years beginning July 1, 1861. At the expiration of this period he was to get $840,000.

In the meantime gold was discovered in Idaho and Montana, and Holladay, encouraged by his big subsidy from the Government, put stage lines into Virginia City, Montana, and Boise City, Idaho.

In 1866 the Butterfield Overland Despatch, an express and fast freight line, was started above the Smoky Hill route from Topeka and Leavenworth across Kansas to Denver. Within a short time this organization, mainly because of the heavy expense caused by Indian depredations, and was consolidated with the Holladay Company. Just prior to this transfer, Mr. Holladay received from the Colorado Territorial legislature a charter for the "Holladay Overland Mail and Express Company," which was the full and formal name of the new concern. This corporation now owned and controlled stage lines aggregating thirty-three hundred miles. It brought the service up to the highest point of efficiency and used only the best animals and vehicles it was possible to obtain.

In addition to his federal mail bonus, Holladay had the following rates for passenger traffic in force:

In 1863, from Atchison to Denver $75.00
In 1863, from Atchison to Salt Lake City $150.00
In 1863, from Atchison to Placerville $225.00

In 1865, on account of the rise of gold and the depreciation of currency, these rates were increased; the fare from the Missouri River to Denver was changed to $175.00; to Salt Lake $350.00. The California rate varied from $400.00 to $500.00. A year later the fare to Virginia City, Montana, was fixed at $350.00 and the rate to Salt Lake City reduced to $225.00.

These high rates and Indian dangers did not seem to check the desire on the part of the public to make the overland trip. Stages were almost always crowded, and it was usually necessary for one to apply for reservations several days in advance.

Late in the year 1866, Holladay's entire properties[[40]] were purchased by Wells Fargo and Co. This was a new concern, recently chartered by Colorado, which had been quietly gaining power. Within a short time it had exclusive control of practically all the stage, express, and freighting business in the West and this business it held.

Meanwhile the overland stage and freight lines were rapidly shortening on account of the building of the Pacific railroads, and the terminals of the through routes became merely the temporary ends of the fast growing railway lines. By the early autumn of 1866, the Kansas Pacific had reached Junction City, Kansas, and the Union Pacific was at Fort Kearney, Nebraska. The golden era of the overland stage business was from 1858 to 1866. After that, the old through routes were but fragments "between the tracks" of the Central Pacific and Union Pacific roads which were building East and West toward each other.
