The first building erected after the founding was a store, followed by a Baptist church, a schoolhouse in 1856, another mill, two hotels, three more general stores, a plow factory and two wagon shops. By 1865, Vandalia had nearly 400 residents. The Des Moines Valley Railroad met with community leaders to discuss the possibility of a rail line connecting Vandalia, but this did not occur. Businesses left Vandalia in favor of railroad towns.[3]
In the early 1900s, Vandalia was home to J.L. Cavett's general store.[2]
The population of Vandalia was 301 in 1902,[5] and 310 in 1925.[6]
