NS 63V, known as "Oscar", has one of last summer's run of AC44C6M's from Juniata Shops trailing westbound on March 25. 63V hauls New Jersey trash to Mingo JCT, OH.
I believe it is tagged that after Oscar on Sesame Street. He sings "I love trash" and lives in a garbage can. The whole train is trash cans.
It looks to me that NS only washes its locomotives when it's prepping them for paint. NS 4500 was released from Juniata last August.
