Yes they still get cars. And yes, the local comes up from Kenwood to switch Mohawk. The local is at Kenwood working, typically 7 days per week. So I assume they run to Mohawk paper on an as needed basis. In the last year or so I have only seen boxcars being switched but in the past I have seen tank cars too. Mohawk Paper runs a warehouse at the Port of Albany next to the Port office building. This warehouse has a siding with numerous loading positions. This facility is switched by the Albany Port RR and seems to have a lot of boxcar traffic. I have seen 4 or 5 cars spotted there at a time and I recently saw them get a switch on a Saturday. So Mohawk Paper seems to be a good user of rail between the 2 facilities.
The CP Kenwood local works Kenwood Yard, Global Propane, Surpass, and Mohawk in Cohoes. Global and Surpass are very active customers.
