The N' Crowd's Bayou City and Gulf RR is divided into eight districts or sub-districts currently.

  Sub-districts

Sub-districts X1 - X4 are on the PM42 associated with the command booster; sub-districts Y1 - Y4 are on the PM42 associated with the ancillary booster.   The entire lower level is Y4.  Y3 has two disjoint pieces.   X4 is entirely a reversal section as is Y2.
