Remarks: Q139 used to be a short 'one-hit wonder' consist of a couple dozen containers or so pulled by a single locomotive, usually an AC6000 or GEVO. However, the economic downturn has seen it take on additional traffic as CSX rationalized its schedule. On February 7th I got my first look at the result - a Jekyll-and-Hyde consist of 49 containers and 95 cars of general merchandise, all pulled by ES44DC 5477, SD60I 8733 (ex-CR 5601), and AC4400CW 366.
