The Topographic Map above displays Tamaroa as a Railroad Town. In the 1910s,
the Illinois Central Gulf R.R. ran N & S between Centralia and Carbondale while
the Missouri Pacific R.R. ran E & W Between Mount Vernon and Pinckneyville.
The crossing of these railroads required that personnel live there to maintain the crossings
plus control the passing of trains. This fact caused the town to have
a communications system where the TRI COUNTY Telephone Company
had its own Operator in 1886. The Company served in Three Counties.
