Sonic Bonnet loops Marsden
CHOCOWINITY, NC — The Sonicboom or Sonic Bonnet NS 4000 was Norfolk Southern's first GE AC44C6M — a Dash 9 rebuild in 2015. She visited Marsden Yard in Chocowinity, NC on July 12, 2018. Here she is finishing a loop of the train to put the 4000 on the point instead of #2. The air conditioning went out on the SD70M-2 teamed with it that day causing the switch.
