What was the last freight car built by GATX? - Trains Magazine

East Chicago was where nearly all of the Airslide cars were built.  Tank cars were mostly made in Sharon, Pennsylvania.  

I have asked an expert, whom I hope will be weighing in for us sometime.

I had a reply on here earlier mentioning the last Airslide car being built at East Chicago in April 1985 (GACX 56385); I don't see that response today. 

Carbuilding operations were bought by Trinity Industries, and the East Chicago and Sharon plants were closed immediately.  I know that Trinity-built tank cars were showing up in the GATX lease fleet by 1984.  Trinity continued to build Airslide cars at its Fort Worth plant for a few years, but they were eventually supplanted by Trinity's own designs (Airslide cars were expensive to build and had much smaller capacities than competitive designs).
