#3 was originally built and even lettered for the Denver and Rio Grande as their #13 'Moscao', but was rejected by the road for unknown reasons. She was the first narrow gauge consolidation built in the US. The were slightly larger than the Clas 56 consolidations the D&RG bought in 1878 and smaller than the Class 60 (C-16) the Rio Grande would eventually own.
Arriving at the EBT in November 1873, #3 inpressed the railrod as it was much larger than Moguls #1 and #2. The EBT it enough to order two more, #4 and #5 of identical design. As built for the D&RG and like #1 and #2, the locomotive had a short smokebox, diamond stack and cantilevered square kerosene headlight, which it likely retained during its early years on the EBT. Also like the earlier power it had a crosshead feedwater pump, except that it was outside the crosshead. Unlike the early Moguls, #3 had a four axle tender and single steam dome.
#3 was reboilered in 1891. Sometine prior to 1906, and likely at the same time as she was reboilered, the locomotive received new, higher running boards, a straight stack, extended smokebox and round kersene headlight. By 1896, #3 had relinquished the name 'Rockhill' to the new Mogul second #5.
She was finally rendered suplus by the Mikado 12 and Prarie 11 and was sold to the nearby Tuscarora Valley Railroad. She worked there until being scrapped in 1917.
