 The route runs parallel to the Columbia River's bank, and the river is visible most of the way. In a few places, the tracks are carried on low trestles over the water. The line passes through the NRHP-listed Downtown Historic District, and its westernmost section passes under the Astoria – Megler Bridge. To the east of the Maritime Museum, at 20th Street, it passes a former Spokane, Portland and Seattle Railway depot built in 1924. The fare has always been $ 1, with an all-day pass available for $ 2. Around 2006, operation was extended east from 36th Street to 39th Street, making the line about 3 miles (5 km) long.
