Between 1924 and 1930, the Delaware & Hudson had three high-pressure locomotives with a 2-8-0 wheel arrangement built by ALCO-Schenectady. What they all had in common was the Mühlfeld boiler, which had a large water tube firebox. At the front there were two large drums that lay on top of the boiler barrel. All three locomotives were two-cylinder compounds with a two-axle booster on the tender.

The first was number 1400 named “Horatio Allen”, built in 1924. It had a boiler pressure of 350 psi (24.1 bars). In 1927, No. 1401 “John B. Jervis” was built, which had a boiler pressure of 400 psi (27.6 bars) and smaller cylinders. The boiler was later fully enclosed. In 1930 the No. 1402 “James Archibald” finally followed with a significantly increased boiler pressure of 500 psi (34.5 bar). Its boiler was also fully enclosed.

Since the significantly more complicated maintenance was not worth it in any way compared to the gain in efficiency, all of them were retired by 1935. In 1933, the D&H had No. 1402 “L.F. Loree” built as its fourth high-pressure locomotive with a 4-8-0 wheel arrangement, which suffered the same fate.
