my ESPEE MODELERS ARCHIVE
California's Railroad to the U.S. 1861 - 1996
Southern Pacific SD7R
1500 - 1542
43 units rebuilt
Surprisingly _no_ SD7R's were painted in the Kodachrome scheme...
see also SD7 Info page.
see also Image Library of SD7/9 Detail Shots.
see also Pix of 1518 in Denver.
Beginning 1979 and continuing thru to 1980, SP's Sacramento Locomotive Works rebuilt the SD7's into SD7R's.
Externally, which is all we modelers care about, the following changes took place:
According to Joe Strapac in Southern Pacific Historic Diesels Vol.4 all SD7's were rebuilt without dynamic brakes...
Note: Evidently all SD7R's had their dynamic brakes disabled. #1500 - 1529 simply had them disconnected. #1530 to #1542 had the dynamic brake components removed. Externally, some had just the fans removed, and the holes plated over, others had the fans and grids removed, with the holes plated over. They all retained the dynamic blister. Both books by Joe.W.Shine, and SP Historic Diesels Vol.4 by Joe Strapac have good photo's of these units.
