Below in the table is my original information on these Sets created before 2000.

A fellow member of the Train Collectors Society, Rolande Allen, has spent considerable time and effort researching these Sets and the subject of North American Tri-ang.

The results of his labours and on-going research can now be found on his Web Site at:

I highly recommend that you visit this wonderful addition to the Tri-ang collecting hobby/obsession, and I congratulate him on his efforts.
