Hi there...if you hover on the coupons tab at the top of the page a little menu will pop up and one of the headings say trains" when someone has created a new train you can view it in that thread and post a message in the thread saying you would like to board the train and then Private message the conductor with your name address and any other infornation the conductor has asked for in the thread. I hope that helps answer your question...if you have any more feel free to PM me and I'll help you out as best as I can...have a great day!
