The 8-inch Gun M1888MIA1 Barbette carriage M1918 on railway car M1918MI was a U.S. Army coast artillery gun, used during World War I, and World War II.

History[edit]

The M1888 8 in (203.20 mm) gun was a coastal artillery gun mounted on a barbette carriage. At the start of World War I, the United States and its allies needed a medium range heavy artillery piece that could be transported easily. The quick solution was to take the existing coast artillery guns and mount them on a drop bed rail car. This was done with a number of different weapons, like the 10 in (254.00 mm), and 12 in (304.80 mm) guns, as well as mortars.
