Altamont
Confederate Railroad Raid
On April 26, 1863, a detachment of Confederate Capt. John H. McNeill’s partisan rangers attacked the Baltimore and Ohio Railroad facilities here at Altamont. They were part of a larger group that entered Oakland that Sunday as Confederate Gen. William E. “Grumble” Jones led an incursion into West Virginia and Maryland to hamper the rail movements of Federal troops and supplies.
Capt. Edward H. McDonald led the ranger detachment into Altamont to destroy the facilities here. First, the rangers cut the telegraph wires so that other stations on the line could not be warned. Then they destroyed the switching machinery and the switches in the track (Altamont was a switching area for “helper” engines used on the 17-Mile Grade).
The rangers also captured a locomotive at the top of the grade here. A soldier climbed in the cab and opened the throttle, intending to reverse it downgrade and either wreck it on a curve or crash it into an approaching train. The engine ran forward rather than backward, however, and headed towards Oakland. It would have wrecked at the burned bridge west of Oakland that had been burned by another detachment of rangers that morning, but it ran out of steam first.

4. The Tracks at Altamont, Looking East
It's all downhill from here. 17 Mile Grade begins here. It is the steepest railroad grade on the east coast; more than 2.5% in places. And plenty of curves. Dozens of trains have wrecked going down this grade, some recently. The track repairing equipment is parked on the siding used to hold helper engines that have just finished helping a train uphill.
