One of my brothers-in-law told me that he briefly worked for the SP when he was younger, kind of a summer job. He was an electrician-trainee for the SP and had some stories about changing out relays in diesel engines when they were under load on the Tehachapi Loop. This would have been around 1960 (I’m guessing).
Any interest in, say, some video of a short interview with him?
If so, any questions you want me to ask?
