Mahalasville, also known as Vansickel, Vansickel Mill and Vansickel Station, was once located on the Jackson-Washington Township line. The map shows Mahalasville in eastern Jackson Township, Section 30, and western Washington Township, Section 25. This is about half-way between Martinsville and Morgantown in Morgan County, Indiana, on Mahalasville Road and Voyles Road.

The railroad, which was key to the health of the town, brought the train, nicknamed "Old Jerk", into town twice a day. By the 1870s the town had grown to a population of 270. The F.F.& M.,(Franklin, Fairland and Martinsville); the C. & M.,(Cincinnati and Martinsville); and the N.Y.C.,(New York Central); are the companies which controlled the line at various times in its history. The schedule of the C. & M. in 1873 was; Martinsville, Indiana to Vansickel, Morgantown, Samaria, Trafalgar, Branch's, Franklin, Urmeyville, Niedham, Baggstown and Fairland, Indiana.

     Mahalasville's decline came with the decline of railroad service to the town. The railroad ran on the south side of Old Railroad (450E). In 1922 the mill, which had been built in the 1840s and rebuilt in the 1870s, burned. The mill stood on the southeast corner of the intersection of Old Railroad and Mahalasville Road. The stone foundation blocks are still visible. The fire was reported to have been caused by a steam boiler explosion. The feed store burned in 1936, the Baptist Church was torn down, as was the Methodist Church and by 1978 the site of the blacksmith shop was a garden. All that remains of the old village is the memorial marking the site of the Methodist Church and the cemetery at the top of Voyles Road. Jacob and Mahala Vansickel, the town's namesakes, lie there.
