Yes, REA made track.
From my web site:
1984 - 19 June - REA and LGB enter into US distribution contract.
1985 - Aristo-Craft started making G Gauge buildings by licensing some Delton wood structure designs and converting them to plastic kits. These were successful and later converted to fully built-up and painted items. (from Jan-Feb 2010 Aristo-Craft"Insider")
1985 - October - REA sues SUPER SCALE MODELS, LTD.; and Charles C. Merzbach (they were selling “gray market” LGB) (they eventually lose)
1988 - January 4 - E.P. Lehmann terminated the contract.
1988 - REA teamed with Aristo-Craft to make 1/29th Lionel (Lionel is a trademark of Lionel Inc. and not in any way connected to Aristo-Craft) sized standard gauge trains in 1988. Aristo-Craft had designed and started selling a track line and then merged it into their partner REA. The track had the highest percentage of copper in the market plus screwed together rail joiners. (from Jan-Feb 2010 Aristo-Craft"Insider")
1988 - “Periodically, I get e-mails about discussions on other websites and they want my opinion. The most recent one asked about our Long Steel Caboose, which is the first product we ever made. This was some 24 years ago that we designed it and introduced it in 1988. At that time our direction was to be a toy train company and we were making a scale popularized by Lionel (trade mark of the Lionel corporation) in the first part of the century. Our partner at the time under our REA trademark was Bill Lamping and he wanted to make his favorite Lionel caboose. This was the model for our first product, not a scale model of a real caboose.” (Lewis Polk, Aristo-Craft forum 03-05-2010, 11:38 AM)
1988 - “The REA trade name was used during our partnership with Bill Laming and when that was dissolved we continued the line under the Aristo-Craft name.” (Lewis Polk, Aristo-Craft forum 03-05-2010, 04:12 PM), NOTE: it seems that the REA name was a partnership, and that partnership was dissolved. The 1990 REA catalog stated: “A joint venture of Polk’s Model Craft Hobbies, INC, and Railway Express Agency, Inc.”, the address on the catalog was 346 Bergen Avenue NJ.
1990 - Aristo-Craft and REA parted company as REA was spending its time and fortune in litigation against another company. Aristo-Craft also moves its production from Korea to China. (from Jan-Feb 2010 Aristo-Craft"Insider")
