Only 30 minutes after the bright sunny shot of the 8341 at CP Burn, the 8341 and 19G head west through Emmaus. The clouds had moved in with a fury right before the shot was taken and would stay for the rest of the day. Meanwhile, the 8341 plus 2 more Norfolk Southern C40-9W's struggle to get the lengthy 19G up to the track speed of 50 MPH which runs between here and CP Blandon.
