Two years after the beginning of the work, “brigades” of horse-cars were in regular service to Ellicott’s Mills; by the first of December, 1831, trains—steam-drawn—ran through to Frederick, Md.; five months later, to a day, they had reached Point of Rocks on the Potomac, seventy miles from Baltimore. At Point of Rocks the road was halted for a long time. The power of the powerful Chesapeake & Ohio Canal, which had been great enough to keep State or national grants from struggling railroads, was raised to defend its claim to a monopoly of the Potomac Valley, by right of priority. This right was sustained in the courts, and the railroad held back two years, until it could buy a compromise.

In 1835, a highly profitable branch was opened to Washington, while early in the following year, trains were running through to Harpers Ferry, at the mouth of the Shenandoah.

During that same Summer of 1835, definite steps were taken toward the extension of the railroad to Pittsburgh, as well as Wheeling. But it was three years later before the struggling company was ready to make a surveying reconnaissance of these extensions of the road. All through that time actual construction work was slowly but quite surely progressing westward from Harpers Ferry, and on November 5, 1842, trains entered Cumberland, the one-time objective point of the enterprise.
