The Elucubrate Express

Hello everyone.
For sometime now I have been thinking of this interesting story ideal. It is one that I need your help with. The story will take place on an old steam train in the old wild west. It is a express train that goes from New York to Seattle with only one stop in Chicago. There is going to be a murder that will take place in the course of the trip. The crew are in need of help for they can not stop the train for anything. It is up to the passengers to help find out what is going on.
How would like to ride this train?
This is my ideal. Each of you, if you like to buy a ticket, would be a passenger on the train. As the story is unfolding each and everyone who has a ticket will be able to help decide how the story plays out.
Now how will I do this?
First what do you want your character to be like?
What name do you want and what do you look like?
Why is your character boarding the train?
You can be anything you like just remember to think of the old west when you do.
I will be the director of this story and you will be like a co-writer. When there is a scene when your character is in it I will ask how would you react, respond, do, and say. I will edit it the best i can to work it into the story. I will always ask you what you think of it before I move on to the next scene. This may and will take some time.
I do not know how this is going to work nor how the story is to go. All I can say is at some point someone will die. Maybe even more than one. I do not know who, when, or why yet.
So if anyone would like to be apart of this please sign in and take a ticket.
This should be very interesting and fun.
Thank you,
