In 1911, the line from Multnomah Village was upgraded from a single-track on a large trestle along today’s SW Maplewood Avenue to a double-track along today’s SW Multnomah Blvd, with several smaller trestles. By 1912, the southern line was extended all the way to Eugene, and 22 trains per day arrived into Garden Home from Multnomah Village.
