Ryan,
MLW never built C420s,but was still building RS-18s for awhile after the Centuries
were introduced.
after CP8300 Alco built the 15 unit EL C424 order,then the 1st C420s for L&HR
were built,about 5/63.
Alco also built at least 1 RS-36 for Tennesse Central after the L&HR C420s.
not exactly a smooth transition period.
