Very unusual circumstances find NS train 40T waiting at Emmaus. The train which one ran on the Reading Line to Allentown was switched to the Lehigh Line for its trip north and then heads west via the Southern Tier however for two days the Lehigh Line was shut down with fallen trees caused by the great amounts of snow which fell on Christmas day. Canadian National 5722 is an SD75I and is followed by an SD40-2, CN power is extremely common to this train and its counterpart 41T.
