We used to have a few folks active in TT scale, who were posting here. I could never understand how the scale never took off. It is an excellent size.
Haven't seen TT since the '80s. I do remember the discussions on this board and had hopes it may take off here.
The only TT Scale I've seen lately was at an Antique Co-Op down in the Southern Tier of New York. It looked to be from around the 1960s or earlier.
