Steve Drassler adds on 5/4/20, "Aaaah, 7123, one of my past girlfriends. I have not-so-fond memories of trying to caress you and your slippery wheels and smokey stack and crankcase ventilator around the dance floor of Anchorage yard. Our relationship was a troubled one. You were always exposing yourself with all that glass in the back, making us cold in the winter and hot in the summer.  You had a long, ungainly throttle lever and weak legs.  I liked bigger girls but ,sadly, you were a waif of a lass, not heavy enough to easily stop long drafts of bled-off cars. Not to mention your wheezing breathing through ancient air-brake valves and cylinders; you were a relic of a bygone day and more suited to dancing around a "flat" flat-switching operation and not trudging up and down the side of a hill like the Anchorage yard in your delicate slippery brake shoes. When you did lean into it going towards Whitney, everyone looked and listened because you purred like no other kitten in the litter. RIP 7123. Alas, I never met your sister. Where are you now, Birchwood or in a museum?"
