While trainwatching at NS's Conway Yard (regretfully no heritage units seen), I found a slug set that had an ALCo style nose on one of the slugs. Is it an old N&W RS11?

I've not followed the slugs in 20 years, but there used to be a number of Also RS-11s (I think they were 11's) that Conrail made into slugs and paired them with SD38-2s for hump yard service. I'm assuming that these are those just with a newer coat of paint.
former PRR8675 RSD12

I have seen several of these units, always have heard them refereed to as calf's. See them often in the Enola Yards on the west shore of Harrisburg as recently as last Thursday.

A calf would have a prime mover and main generator, but no control cab, and be MU controlled from the cow control unit.
A slug has no prime mover nor main generator, but receives its electrical traction power from the "mother" unit. The electrical connections between slugs and mother units contain high voltage/high current traction motor cables.

What you saw is a pair of Conrail's MT-6 (Motor Trailer, 6 axle) slugs (not sure what NS calls them), built mostly from Alco RSD12 units. I believe two were built from RSD15's; they're longer but also classed as MT-6.
The slugs built from RS11's are 4-axle MT-4's, and were usually mated with GP10 locomotives.
