The 1918 consular report said that this railway connected Peru's southernmost port of Ilo with Moquegua, which was 62 miles (100 km) away in the province of the same name. The IaM opened in 1873 after a three-year construction period, but was shut down by the Great Pacific War of 1879-1883 and only reopened in 1907.
The modestly scaled Mogul was the first new locomotive on the line, which had a total of three (the other two built by Baldwin; see Locobases 13472-13473.
