I'm thinking of adding some Athearn Genesis GP38-2s to the fleet, but would like to know how the drive quality compares with the Atlas GP38/GP38-2 (and Kato SD38-2s, for that matter), and how well the two can be made to MU with DCC. Any input would be appreciated.

In the picture in this link http://trainweb.org/galt-stn/cproster/locomotive/1400s/cp1416.htm can someone tell me what the quarter circle extensions are on each side of the diesel's roof are called and what purpose did they serve?

I have two of these particular Athearn diesels, bought in the mid 1980's and stored for some years. Yes, I know, the original metal used for electrical connections has rusted, a bit.  However, that's not the issue.  The issue is noise.

A special limited edition of EMD SW diesel locomotives is now available for order. New York Central, Norfolk & Western and Penn Central. Each series is only 15 pieces.
