18 has never pulled the double deck C-1 cars, except perhaps while switching in the yard. 18's regular consist is a modernized X-IC heavyweight lounge car, X-ATSF dome, X-SOU heavywieght coach and X-SOU heavywight open car Lookout Mountain. We planned to run an all heavyweight consist for our photographer's special, but it got canceled by lack of interest.
People like the domes, they buy the tickets. People who complain that the consist isn't authentic looking, usually just take pictures and don't buy tickets. Thier vote doesn't count. I tell them to go find another SG steam show that has longer, steeper grades and covers 124 miles each day.....
