 Eventually the northern portion of the DuPont Farm and Ammunition Storage property was eventually annexed by the Village of Midlothian, while the rest of the DuPont property was acquired by Cook County, Illinois and developed into what is now the Midlothian Meadows Forest Preserve (part of the Cook County Forest Preserve system)

The Village Midlothian acquired a portion of a second railroad for a relatively short period of time, although when the Midlothian Country Club was annexed into the Village, its history became a part of the history of Midlothian not as a next door neighbor, but as a part of the community.This means the Village of Midlothian with its present-day boundaries had two railroads for approximately 50 years, despite removal of all tracks and equipment in less than 30 years from the date of incorporation of the Midlothian - Blue Island Railroad.Despite land speculation and sporadic development growing from the direction of what would become the Village of Robbins in 1917, dirt roads continued to act as an uncontrollable barrier to a variety of economic activities, such as delivering goods and services.
