Four big Alcos from two of my favorite roads - you just made my day.I got this picture just north of Wampum, Pa in May, 1977. Conrail was using a bunch of CN MLW's at the time too.
WNYP, last I heard, has a couple C636 and several M636, but I don't know how many of them run. D-L has a C636, a M630 and a M636.We still have some 4 axle Century models running and there may be a 6 axle still running on the Western New York and Pennsylvania, but there surely are a few more hidden somewhere.
