Dunno but this is also about 1977-1978 based on the other items on the spliced in film
I like the warm colors of this one, also from April of 1973.
Cabooses have always been good image subjects and this one is no exception. Note the LOCAL designation. The inspection black block stenciled in white has 9-24-72 (maybe and 8 ?) and that helps explain the very fresh look to this bit of history.
This is a favorite of mine, an S2. The working class working on a Spring day. According to the RR Archives built January of 1948 and Retired in December of 1975.
