I'm watching this one with great interest , Andrew , since I downloaded this paper model a few weeks ago but haven't touched it yet ....or any of my other paper downloads for that matter . Too many other things on the go , right now , but I will get to it and use this thread for references . Looks good , so far !

G'day Folks.
First, thanks for the compliments and encouragement Terry, I will be getting back to this project soon, I am in need of finishing off some other projects so that I can have wheels rolling on rails a lot more frequently than they are now. My Blog will reveal some of my latest activity.
Second, some really good news in that a member of a Mexican T-TRAK group has actually built two of the structures to completion, including the internal overhead crane etc on one of them!!! You can see it at the 3min 30 sec mark of Video 1 at:

The video quality suffers bit from lower levels of light but you can see enough to understand that Carlos has done a really good job.
