Route

The eastern end of the line is at Hinkle, Oregon, where it meets the La Grande Subdivision. The Oregon Trunk Subdivision of the BNSF Railway crosses over at Oregon Trunk Junction, 10 miles (16 km) east of The Dalles, Oregon. At Troutdale, on the eastern edge of Portland, the line splits: the Kenton Line continues northwest through northeast Portland, while the Graham Line heads due west into downtown Portland. The two lines meet at East Portland, just across the Willamette River from Portland Union Station. The line continues across the Willamette over the Steel Bridge to Union Station. There is no track connection between the Graham Line and the Steel Bridge.[1]

Operations

As of 2022, the Portland Subdivision hosts no passenger traffic, save for the small section in Portland from Union Station across to the Steel Bridge to the Brooklyn Subdivision.[2] This hosts Amtrak Cascades and Coast Starlight, both of which operate between Portland and Eugene.[3] The Pioneer, discontinued in 1997, provided service over the whole route, including stops in Hood River, the Dalles, and Hinkle.

As of 2003 the line handles between 22 and 24 freight trains daily.[4]
