As of 2006, INPR operates tourist trains and "river and rail" trips in the Payette Canyon that allow riders to ride a train in one direction and return by river raft on the water of the North Fork of the Payette River. Both the Oregon portion and the Payette River line were historically built as logging and lumbering lines with large Boise Cascade mills located in nearby communities, but some of those mills were disbanded and closed in recent times, consistent with a decline in logging and lumber processing in much of the Northwestern United States . As of 2012 The Idaho Northern and Pacific serves the still operating Boise Cascade lumber and plywood mills in Elgin, Oregon, the Boise Cascade particleboard plant in Island City, Oregon, and the Boise Cascade sawmill in La Grande, Oregon.
The Boise line was operated for freight connection with Union Pacific at Nampa and to serve the industrial areas in East Boise with rail service, until the Boise Valley Railroad took over operations in 2009, possibly as a result of the economic downturn at the time.
Idaho Northern and Pacific's offices are located in Emmett.
