Proper Usage of the R3 Segment in a 210

I would like to know if this is the proper usage of a R3 Segment in a 210


I am looking at this as  "1"  (R302) is the first stop in Milwaukee to identify the first stop
and "2" (R302) to identify the second stop in EFFINGHAM  as per the 204.    The SCAC code in R301 would remain the same, as the carrier is the same.  And the M is to stand for a common carrier. (Describe "Common Carrier?) 

Would it be safe to say that each stop would have a R3 segment associated with it in the 210?

Also would be interested in knowing the use of Code "B" in the R302 segment? And if you use the code B


A 204 is sent to a logistics company with 2 stops, a pick up and delivery. When the load is completed an invoice is generated for both stops to the same BT.

The R3 segment is in the 210 to report interline carrier information. The definition of the R3 is; To specify carrier and routing sequences and details.
The proper use of the R3 is to provide the SCAC of the interline carrier (R301) followed by the routing sequence code, which is defined as; Code describing the relationship of a carrier to a specific shipment movement. Code 1 is defined as ; 1st Carrier after Origin Carrier.
In addition, it can report the charge related to the interline carrier.
The R3 should not be used to provide stop level detail.
Code “B” is used in the rail industry.
