An act of Congress, approved April 1878, gave
the Utah & Northern Railroad Co. permission
to build a narrow gauge line through Marsh
Valley. It reached Oneida by July of 1878, where
the first station was built. The town attained
a population of about 2,000 as it was the
forwarding point for the Soda Springs area
until the Oregon Short Line came to McCammon
in 1882. First post office in this valley was
established, Alma Hobson, postmaster. Oneida
changed to Arimo honoring an Indian Chief.
