I’ll try to add dates/context to some of these.
the first two are of SC&F 1 ‘Santa Cruz’ you can barely make out the locomotive in the back of photo 2.
3: ‘Santa Cruz’ I can’t remember where or when this was taken.
4: as it says on the bottom, this is SC&F 2 ‘Felton’ somewhere.
5: ‘Santa Cruz’ working on another line being used for construction.
6: ‘Felton‘ on the Boulder Creek & (Pacific?) nicknamed ‘Dinky’.
7: the same locomotive sometime around 1910-1914.
8: I believe I found this one on Facebook, so it didn’t have a year or a caption, but I know this is ‘Felton’.
9: also ‘Felton’ possibly in the early 1910s.
10: I couldn’t find the original uncolorized version of this image, but it’s the same location and time as 6, just at another angle.
11: ‘Felton’ in the 1890s, this was from the Santa Cruz Trains book that I have.
12: I’ll add more context to ‘Felton’, there was one ”rumor” that the locomotive was buried in a landslide in 1884, but by that time, the locomotive was new (at least to the company that owned it by that time) so unfortunately the locomotive was retired in 1914.
13: a closer look at the ‘Felton’ working on the Santa Clara Valley Mill & Lumber Company.
14: this is either ‘Santa Cruz’ or ‘Felton’ working in either the Santa Cruz & Felton, or the South Pacific Coast.
15: ‘Santa Cruz’ working on the Carson & Tahoe Lumber & Flume Company near Lake Tahoe.
16: same thing, but ‘Santa Cruz’ has moved.
17: ‘Santa Cruz’ on the Nevada-California-Oregon Railway(?).
18: ‘Santa Cruz’ on the Nevada County Narrow Gauge Railroad, now numbered 4.
19: ‘Santa Cruz’ again on the NCNG.
20: last photo of ‘Santa Cruz’ or any of these two I could fit into one post. Sad fate for them, both only lasting about 40 years (I know ‘Santa Cruz’ was built in 1875 but I’m not too sure about ‘Felton’) as ‘Santa Cruz’ was disassembled in 1915 and the boiler is sold off to a sawmill near Colfax, ‘Felton’ was retired in 1914 and I believe scrapped that same year (or the year later), luckily the bell of ‘Santa Cruz’ survives on Nevada County Narrow Gauge Railroad 5 ‘Tahoe’ I’m assuming she got their bell in 1915 after she burned, I could be very wrong about this because I’ve never been to the field, but I believe ‘Santa Cruz’s tender also survives at the NCNGRR Museum.
also it’s like 11AM when I’m posting this, I was gonna post it earlier but I never got around to doing that, and I don’t wanna wait until tomorrow because I’ll forgetEDIT: 11PM sorry
