Transactions of the American Society of Civil Engineers, Vol. LXX, Dec. 1910 Locomotive Performance On Grades Of Various Lengths, Paper No. 1172

"Transactions of the American Society of Civil Engineers, Vol. LXX, Dec. 1910" by Beverly S. Randolph explores the challenges and efficiencies of locomotive engines as they tackle different uphill slopes in the early 1900s. Randolph uses real railroad data to show that locomotives do not perform as well on longer uphill stretches, acting as if they become weary along the way. Presenting charts and data, Randolph shows how a locomotive’s power to pull decreases the longer it has to go uphill, further delving into topics such as steam production and the locomotive's speed in climbing hills. The work of Randolph is a topic of discussion by engineers as they reviewed, approved and critiqued his findings
