These three railroad interchange amongst each other in 2 interchange locations.
Wichita, KS: KO to SKOL or SKOL to KO.
Tulsa, OK: SKOL to SLWC or SLWC to SKOL.
These interchanges are very similar to regular ICR and ICH. The only difference is we make sure the cars that are delivered off from one railroad are brought online to the receiving railroad.
Sometimes the cars you interchange will auto ICR, but you may have to find the consist in the inbound and bring them on.
