hello im a huge fan of the dmir. (i live only a few hours away) and am researching the rsd-15s they had.i know they had 6 and were rid of them by 1964. ive also heard they were used in two harbors for switching, however in my thirst for knowledge on these i would love to get any more info on them, like photos or crew impressions.for some reason the dmir rsd-15s just fascinate me. but i guess im a big alco fan as well.
