Buffalo still has several industrial critters/switchers in use (and probably just as many still there, but not in use)
Outokumpu American Brass has an Alco S4.
former South Buffalo #92.
believed not in use, little is known about this unit.
"Huntly Plant" (former Niagara Mohawk) in Tonawanda has an Alco S2.
former South Buffalo #64.
also believed not in use.
Tonawanda Coke has an Alco S3, former Maine Central 961.
known to be OOS, replaced by an EMD SW-something which is in use.
there is a former Oxy-Chem/Relco Alco S1 on the south side of Niagara Falls, awaiting transport to its new owner,

More info on the Alcos is here:
I dont keep track of the EMD's or GE's, so im not sure how many industrial switchers are in use in Buffalo..
(someone probably maintains a list!)
probably at least 4 or 5 in use I would imagine, maybe more.
I saw a tiny GE 4-wheel critter down at the Buffalo River industrial area last year, dont know who it belongs to.
