The Gunderson double-stack cars that were produced for MDK K-Line in China could be made articulated. They were not offered as articulated cars, but the sides and ends were designed like the Gunderson Maxi-Stack articulated cars, not the Husky-Stack or Gunderson All Purpose Well Cars. It would be much easier to make the K-Line Gunderson well-car into an articulated car then the MTH Husky-Stack well cars.
