Heffalumps

There was an article (perhaps in MR) in the 1970's called "Horrible Heffalumps", that was about mixed mfr. conversions.  You might try a search for Heffalump locos".  I'm at work, with search rule limitations, so all I found was a copyrighted for-sale photo of a KATY RS3 with a GP7 long hood.  I know that KATY had a reputation for making do with what they had, with some "interesting" results.

sources found using heffalumps and the leads from that reference

thanks,

went to wikipedia "M-K-T RAILROAD"  and there is a photo of RS3 m.  these are the alco rs3 which had emd engins and dynamic brakes with gp9 long hood.  clicked on the photo lead to more information.  also C&NW roster of locomotives showed the M-K-T RS3 m sold to them with some of their history.

AS16 conversion

 There is a photograph of this conversion in Kalmbach's book "the second Diesels spotters guide on page 441. Basically shows the long hood of the AS16 replaced with a long GP9 hood with dynamic brake blister. Road number carried is 130.
