False.

The Union Pacific/Central Pacific was the first transcontinental railroad (completed 1869), but it was not the only one built in the 19th century. Other transcontinental lines were completed later in the 1800s — for example the Northern Pacific (completed 1883) and the Great Northern (completed 1893) — along with southern and transcontinental routes by railroads such as the Southern Pacific and the Atchison, Topeka & Santa Fe.
