Villa Grove is part of the St Louis Hub. VG has had a lot of conductors jump ship to CN in nearby Champaign as of late. In addition to the call of more money with CN, they are also escaping the wrath of some hell bent trainmaster at VG. I guess it's multiple reasons for people leaving. You can work anywhere on the STL Hub you can hold seniority, but since you want to work closer to St Louis, I probably wouldn't tell them at the hiring session that you're really wanting there versus VG.
Anyhoo, other locations you can/will protect in the STL Hub are Salem and Dupo, Illinois and also Dexter, Missouri. As a young guy expect to live on the road at those locations (mostly Dupo) until you can build some seniority.
There are two boards out of VG, the XT21 (extraboard) and the RT24 (VG-Chicago). A friend says the guaranteed conductor's extraboard there pays about $2,300 per half. Not sure how short they are now, but the most recent STL Hub conductor's class started October 8th.
Hope that info helped some.
