I came across these photos when sorting through things recently. At the Rhone Island NMRA North East Regional Convention a few years ago, I saw this extraordinary TTrak module. The quality of the scenery and formatting are so high, that the Contest Judges pulled it out of the on-site TTrak layout and displayed it as a stunning diorama in the Contest Room. Only when looking close at the ends could I see the ends of Kato track joiners that protrude from every TTrak module.
Justin Maguire, MMR built this TTrak module based on an old prototype that used abandoned interurban rails (you can see the old poles for the power line) in the salt marshes near Providence, RI. The module is 4 or 5 feet long and truly a work of art. Justin has other stuff on line with the Little Rhody Division of the NER, NMRA.
A4 is the metric paper size closest to our 8 1/2 x 11 letter sized sheets. The late Lee Monaco-Fizgerald created the concept for TTrak on an A4 art board at a model Railroad convention in Japan some 20 years ago. There is nothing in Justin's module that makes you think of it as a linear or flat A4 sheet.
