Captain Mine-A Total Team Effort

The Captain mine came into being under the following circumstances: 1) Commonwealth Edison had need for fuel for the generation of electricity in their Chicago service area. 2) Southwestern Illinois Coal Corp. had an ample supply of coal in the Illinois No. 6 and No. 5 seams. 3) The Gulf, Mobile & Ohio R.R. had a one-line transportation system with the capability of transporting coal from the Captain mine to Commonwealth Edison. These fortuitous conditions permitted an effective three-way partner- ship to develop. Commonwealth Edison had built a new generating station at Joliet, Ill., across the Illinois River from the existing station, to supplement their power-generating capacity for the Chicago area (Fig. 1). The annual requirement of the Joliet station is approximately 4.5 million tons of coal. From large reserves of coal in the No. 6 and No. 5 seams, Southwestern Illinois Coal Corp. contracted to supply Commonwealth Edison with approximately 6 million tons annually from its Captain mine. The logical carrier was Gulf, Mobile & Ohio, whose mainline travels through this coal field and also passes by the Joliet station on its way to Chicago. This railroad has been moving Southwestern's coal from the Streamline mine for more than 30 years. The basic ingredients of timing, scheduling, moving, and handling were adopted by the three parties, the precise details being worked out jointly. To do this, each group had to know its requirements exactly. The initial schedule was drawn up and tentatively approved, with each party taking a hard look at its own requirements and commitments to make certain that the schedule could be met on a normal daily basis. With only minor changes, the final schedule was adopted, each participant feeling that it had a sufficient factor of safety to maintain steady operation. Each party agreed to help the other in time of emergency. When a delay occurs in any part of the operation, the other
