Three Class I railroads are represented by diesel power at Steamtown's Lackawanna Railfest: CSX ES44AC 909, CP (ex-D&H) GP38-2 7312 and a rather dirty NS Dash-9 9678.
Crazy pool power consists, colorful gatherings of locomotives at a diesel service area, or a mixture of colorful locomotives in storage lines. A minimum of four different paint schemes required.
