Caption: Spring of 1988, a time of much change on the Coronado. Combo's like this were not uncommon at the beginning of 88 , there were also a number of instances with a GP38 and a beetle B unit. The first big change came in May with the renumbering of the GP38's into the 47 and 4800's. I caught my last, the 5529, on October the 11th. Next, starting in summer, F unit and GP9 number's started to dwindle. Summer of 89 there were no F units left and any GP9's remaining in service only trailed. The older GP9's quite often helped with their newly re-built replacements, the 4000 and 4100's. In just over a year, many of the familiars went through some sort of cosmetic surgery or were gone for good. Even the roadbed was getting an update. The sub-grade has been dumped and leveled into place. Next will come what seemed like an endless chain of ballast cars. In the end, the whole tracked must have been raised several inches. Looked great! Photo taken at mile 24.4 at 14:30.
