You know, I used to take the Crescent from NOL to MS (usually MEI, sometimes HBG) numerous times when growing up. Every time, the train generally had 1 to 2 F40's, one baggage car, one crew dorm, three to four Heritage coaches, 1 lounge (usually Heritage, later Amfleet), 2 10+6 sleepers, and the Diner...which was almost always at the very end of the train with few exceptions.
When the Gulf Breeze started it really dissapointed me (hey, it was easy to dissapoint a 12 year old raifan)because I used to love to spend time in the Lounge car and well...no more lounge running down to NOL, just the Diner, and as someone said previously, they sold chips and candy from a couple of baskets set up on a table in the Dining car.
My best Crescent memory was when we took (not knowingly, of course) one of the first trains out of NOL pulled by a then brand new P40. In MEI, the Conductor let me climb up into the cab for a minute and I got to say hello to the Engineers.
