Titanic Train

Titanic Train is a level found in some personalized copies of Super Mario 64. It is described as a large, linear train level with very inconsistent details. The entrance is also inconsistent, though it is most commonly found in a way similarly to the Secret Aquarium. The level is usually reported as a smaller level, and not a full course.

Geography
Despite the geography being very inconsistent, it has been said that the train usually has sections inside of the train and on top of the train. Chuckyas are very consistently said to be on top of the train when a top section is present.

Missions
Despite the level's inconsistent nature, few missions have been said to be somewhat consistent. These consistent missions include:


 * Reaching the end of the train.
 * Finding 8 red coins.
 * Beating a "conductor" boss fight, usually being a Chuckya.
 * Finding 100 coins.

Some other missions have been reported, though are less consistent than the above missions. These include but are not limited to:


 * Activating the train.
 * Finding 5 secrets.
 * Using a cannon to shoot at the star.
 * Defeating every enemy in the level.

Report 1
"Okay, that train level I found. I found it in place of that aquarium level. It only had a star, finding 8 red coins throughout the level. I couldn't actually get inside, and there were a ton of Chuckyas on top of the train. Anyways, I got the star, and then the hole just disappeared. The other hole in the one room led to the aquarium, by the way. I found that out afterwards."

Report 2
"So, yeah. That train level. It was literally only named the "Secret Train", if I'm remembering this correctly. I had to fight this large Chuckya wearing a conductor hat for a star, I had to get the red coins for a star, and reaching the end of the train for a star... Because the Chuckya conductor guy wasn't at the end. I found 2 secrets, though I never found the other 3 so I never found out if there's a secret star. I found like 90 coins, so I probably could have gotten a 100 coin star too. Anyways, I got rid of that copy a while back because I finished the game and I didn't know that train level was unique. I wonder if I could find it again if I got my hand on another copy?"
