Westbound trains leaving the Norfolk Southern Allentown yard must negotiate this broad, sweeping curve after crossing the Lehigh River. With the degree of curvature at this location, the necessary super elevation in the roadbed is quite evident here, as Norfolk Southern ES40DC 7572, with sister 7622 behind, leans hard into the curve, approaching Basin St. and CP BURN, with a lengthy train trailing. With the curvature and steady increase in elevation for the next mile, locomotives work fairly hard on this stretch of the NS Lehigh Line to bring their trains out of the river valley.
