No Polar Vortex in Siberia! Siberia, California, that is ... Perhaps it came west to escape the cold (and I thought Lehigh Valley had the "snowbirds"). Norfolk Southern's Pennsylvania Railroad Heritage unit, ES44AC 8102, threads its way through the reverse curves at Siberia, in California's Mojave Desert, on February 3rd, 2014. NS 8102, NS 9898 and BNSF 670 are in charge of BNSF train Q-NYCLAC1-01A as it makes its way from New York, NY, to Los Angeles, CA.
