Meeting rooms on the mezzanine level are designed for community activities, the existing east wing houses Meridian's economic development agency.

[2][3] The railroading history of Meridian began in the 1850s with the Mobile & Ohio and the Alabama and Vicksburg lines forming a junction at the small community.

[4] The Meridian Terminal Company, composed of officers from the Mobile & Ohio, the Southern, the Alabama & Vicksburg, and the New Orleans and Northeastern Railroad lines, was formed to build a new passenger depot.

The new depot and railway express agency were completed in August 1906 at a cost of $250,000 and constructed in Mission Revival Style architecture.

In June of the same year, the Mississippi Department of Transportation approved the use of Federal Transit Administration planning funds for a feasibility study to evaluate the demand and possible sites for a MMTC in Meridian.

Residents, as well as people with ties to Meridian, are becoming a permanent part of the Union Station complex by purchasing brick pavers inscribed with the names of loved ones, friends or themselves.

The pavers are installed in the brick pathway of a small, landscaped green space linking the tower and east wing to the railroad museum.
