Based on on a railroad 50,000 gallon water tank base. This one piece urethane base should be usefull for those modeling the post steam era as the foundations of abandoned water tanks were common after the end of steam usage. While the tanks themselves were usually pulled down, the cost of removing the foundation was usually not justified and could be seen in the weeds along the right of way for decades.
