Just got back from the area, can provide some insight. A&M has all 5 M420s from Ohio Central on property, but all were in the shop area. They are using 2 of the ex BRC/Hudson Bay Rwy C424s in daily service. I believe it was 601 and 602 were used every night as trailing units on the Ft Smith turn. Also saw C424 600 on the deadline with many parts gone, and the hood sections of one of the other 424s, which has probably been scrapped (assuming that was 604). They also appeared to be cutting up one of the original C420s, but I couldn't make out the number (was one of the 60 series units). The Ft Smith turn now goes on duty at 1800, not in the morning like it used to be, and the Monett job is on days now.
