Alco S2 switchers in Hanover PA.

Ive heard an interesting new story today, and im wondering if anyone can help..
It is said there are two Alco switchers at a Vulcan Materials facility in Hanover PA.
One operating, and one not operating.
One is rumored to perhaps be originally a Lehigh Valley unit.
(I dont think its true, the LV part, but I would like to confirm, or deny, the story.)
I can only find on-line reference to one Alco in Hanover, a former South Buffalo unit, Currently VULX No. 3:

(im not sure of it's SB heritage..im working on that too!)

anyone have any knowledge about these units? and perhaps a photo of the second one?
I would like to track down their heritage, and determine if the LV story is true or not..
thanks!

This past year the WGRF (worlds greatest railfans) Convention, a tongue in cheek group of hard core roster shooters, got into this facility and photographed the locomotives. Do a search for the WGRF and perhaps you can track down a member or two. Try Robert Graham on FACEBOOK he might be able to help.
