Yes, Cartier does have the rebuilt units (IIRC there are 5-6 of them) as well as, I believe, two unrebuitl ones (though they may have long been parted out by now, not sure). Even the rebuilds seem to be largely egtting phased out on the QCM though, even from the work train and log train assignments. So, some or all of them may be or may become available, especially if "the price is right".
MNNR still has the Cat-engined M636, not sure if LAL/WNYP would want this. M&E has already parted out the CBNS 2029, so scratch that idea. WYNP/LAL does have CP 4573, so there is "one" of the 6-8. Also, does the ex A&M 70 currently on WNYP count as amongst those? If so, then we may only eb talking about WNYP looking for "4-6 ADDITIONAL" 6 motor Alcos. ALL 8 units that NYS&W has on their property are "fixable" by anyone with an interest and desire to do so and enouh of a commitment to Alco power to do so. (WNYP/LAL has these) However, NYS&W is doing electrical upgrades, I believe one is done and 2 are in the works right now. SOO- NYS&W may have (FINALLY) also committed themseleves to these units. However, again "for the right price" I'm sure WNYP/LAL and/or SIXX/636 Leasing could buy them back. OR perhaps NYS&W would keep the ones they've got running and dump the others back to WNYP/LAL.
Other than the NYS&W units, the Cartier's remaining units, the IBCX ex CN/CBNS 2028 (which is probably parted out beyond economical repair even for an Alco stronghold... but never say never), the MNNR CAT M636, and DL's units, that's about all the options there are as far as sources of 6 motor Alco/MLws (oh, and the NRE HR616s... but that's also a real long shot).
As for my comment above about WNYP/LAL having "had" the 8 636s, and the nsuing discussion re: ownership thereof, "SIXX" and "636 Leasing" consist of LAL and M&E officials. SO while "on paper they" were never WNYPs or LALs or M&Es....
