Wayback ALCO Machine: Midwest ALCO Wonderland Tucked away in the MNNR roundhouse, 3 ALCO/MLW products are either at rest or stored. ALCO RS-27 #318, and ALCO C424 #314 are visible. The Commercial generally rotates their power as the needs change, however the ALCO ranks on the MNNR roster are dwindling. Of course, 318 is one of only 27 RS-27's built, and one of only 2 survivors, MNNR owns both. Both 314 and 318 are former Green Bay & Western units.
