Transferring 100% of inter-city truck traffic (impractical) to electrified railroads, plus electrifying all (not 80%) of the existing rail traffic, would take about 100 TWh/year or 2.3% of total US electrical demand. Electrifying 80% of railroad ton-miles and transferring half of current truck freight to rail would take about 1% of US electricity. 1% is an amount that could be easily conserved, or, with less ease, provided by new renewable generation and/or new nuclear plants.
