Been working on railroad for 12 years. Most of the time like T said, I hit the evenings and blow off some steam. If I don't make my breakfast I will do a 4am workout. Having the proper food when you are in the middle of nowhere is hard sometimes. Cold food or spoiled, take your pick
Depending on how you keep you're food sealed, take some ice packs throw some protein bars in there and a few muscle milk juice boxes.
