Like the 4-4-0 shown in Locobase 9681, this engine was acquired by the Easton, PA-based West End Railway Company to operate on a narrow-gauge line at the 1876 Centennial Exhibition.
General Manager R W Flower, Jr sent a letter to Baldwin recounting the service both the Delaware and the Schuykill (a 4-4-0) had rendered during the the Exhibition. Delaware operated for 131 days after its arrival on June 9:
"These engines came under my daily supervision and did their full share in transporting over four millions of passengers [at 5 cents each] on this now famous little railway.
The gauge of the line was three feet, with double track three and a half miles long, or seven miles in all. For its length it was probably the most crooked road in the world, being made up almost wholly of curves, in order to run near all the principal buildings on the Exhibition grounds. Many of these curves were on our heaviest grades, some having a radius of 215, 230, and 250 feet on grades of 140 and 155 feet per mile. These are unusually heavy grades and curves, and when combined as we had them, with only a 35 pound iron rail, made the task for our engines exceedingly difficult.
"The usual load of each engine was five eight-wheeled passenger cars, frequently carrying over 100 passengers per car. On special occasions as many as six and seven loaded cars have been drawn by one of these engines.
"Each engine averaged fully sixteen trips daily, equal to fifty-six miles, and, as the stations were but a short distance apart, the Westinghouse air-brake was applied in making 160
daily stops, or a total of 25,000 for each engine. Neither engine was out of service an hour unless from accidents for which they were in no way responsible."
In 1877, it went to the Denver & Rio Grande as their #19, the Monte Christo. In 1899, the engine went to Arkansas Valley Smelter in Leadville, Colo.
