Bill and all,
 
I'm sure Bill is referring to Citizens Coke and Gas Utility in Indianapolis.  It was shut down over a year ago and is being dismantled as we speak.
 
CC&G coke was a good source of car loadings for the Monon and NKP in our era.  They also shipped tar and molten sulfur, both by products of the coke making process. I was surprised to learn that a lot of the traffic on the Monon went to smaller mills and foundaries all over the midwest. 
 
I had incorrectly assumed that the loads always went to the large mills in the Calumet Region.
