Well folks, I am an admitted "tank - a - holic" and the last time I posted to this was mid June, so here are my latest.
The Lionel # 17899 Unibody NASA tank car. From around 1990.
The Lionel Lines #36117 2 D tank car in blue, note actual sprung trucks from 2008
The Lionel #16144 SANX (San Angelo) 3D tank car from 1995. Note again actual sprung trucks.
Best Wishes
Don
