When the domestic intermodal container market settled out in the late 90s, the 53' long container emerged the winner. Car builders responded with new wells of like size to accommodate the new standard. Introduced in series service in early 2000, Thrall's triple 53' articulated well car was certainly the best looking of the 53' wells. Angular wheel cutouts, 3 flared-bottom wide and 8 narrow side posts give this intermodal age well car character.
 
Each model has 3 wells, A, B and C, walkway variants specific to prototype, etched metal detailing, detailed air reservoirs and detailed brake valves and sharp hand grabs and stirrups plus floor pin holes for Atlas and other brands of containers. Cars run on 18" radius but 22" radius is recommended.
