The MOS are supervisors of the lower ranks, and makes sure that things go smoothly.

Recently, there were three MOSs hired (Door_Mat, Jack and Tesco) for their responsibility and great work in Stepford County Railway. This means that this rank will likely not be vanished in the future updates! There are currently no ways to apply for this rank, however experienced High Rank may get hired by the Head of Operational Standards, cg7033.
