The past few years there has been a nice increase in the amount of information about the WDW monorails on the internet. I refrenced many of these sources in writing the latest update to my web site.

Since the information about those trains is closely related to the opening days of the park this addition has been made to one of the earliest chapters . I'd love for our "experts" to look over the information I have there and see if they see any errors, or if any of you know things about the Mark IV trains that I do not I'd love to know those too. For instance how many five car trains were there? Did they ussualy only run the five car trains on the resort loop? Did they add any cars to any of the trains that were originally five cars?
If so does that perhaps account for the long delay between the delivery of the first ten trains and the last two (see the list on the page I wrote for details)?
