Hi guys,

thanks for posting these interesting links. These copycats in California not only copied the engine I am just building for my Sonora Mining Company. They als took advantage of the name (Santa Rosalia) because my layout is called Santa Rosa N.M., it was named after my wife.

Keep the good things coming.

Wolfgang C.

Wolfgang-feel free to post pics of your loco. Sounds interesting.

A little basic geography: The Compagnie du Boleo railroad and mines were located in the small port town of Santa Rosalia, which is located about 500 miles south and east of San Diego on the Gulf of California/Sea of Cortez. Despite the fact my map shows a bigger font for "Santa Rosalia" than it does for San Diego, Santa Rosalia is a small town of +/-10,000 folks:



And a quick (read not field checked for accuracy) view of the Compagnie du Boleo railroad. The 3' narrow gauge operated approximately 30 miles of track from several mines to the mill and smelter at Santa Rosalia, not to mention the trackage around town and onto the docks of the port:

The "rusty carcass" is one of four of the little Baldwin 0-6-0 tank locos around town in various stages of preservation. Iirc, the Surviving Steam Locomotives site only lists three, but anyway, here is the Baldwin Builders photo of one of them when she was brand, spankin new in 1899:

https://digitalcollections.smu.edu/cdm/singleitem/collection/rwy/id/380/rec/1


This is the first loco most visitors to Santa Rosalia see when the pull into town-it is located in the plaze and appears to be the best preserved. According to Kirchner, this is locomotive #7 and was the last operating locomotive, operating to approx 1970 or so when the smelter shut down:


This is the same locomotive I posted in the earlier photo-it is located behind a fence atop the ore bins of the smelter:



will post photos of the other two in a seperate post....

The remaining two locomotives are found in a median on a boulevard in the French part of town (note the architecture-will touch on that later), which is on a Mesa overlooking to Gulf of California. Other than #7 (in the plaza), I don't know the numbers/names of the locomotives



And this one is located on the same boulevard across the street from the museum:



Does anyone have a theory of why the Boleo locomotives have a small "window" on the lower part of the cab? I believe they are found on both the engineers and firemans side of the loco.

Excellent photos & map, thanks Duane. I cannot find much info on C. Bolero by searching from a UK internet address.

I have a vague theory about the cab side sheet "window".

The original, ex-works Baldwin photo has no window. The mechanical injector pump has a normal (automatic) type clack-valve (the valve that admits feed water into the boiler).

But the Boleo locos all have what seems to be a manually controlled clack valve, operated from a handwheel down beside the base of the reverser (quadrant), which must have been damn awkward to operate. The "window" gives direct access to this handwheel from outside.

The only purpose I can think of is that by altering the pipework they were using the clack-valve also as a boiler blowdown valve ??

I have never seen a similar arrangement before so the above is just a semi-educated guess.

Regards,           Michael

Michael-you clearly have a better understanding of steam locos than I do!

Here area couple of closer pics of #7:

Thanks Duane, but now I'm not so sure !.

Correction: I made a silly mistake in haste. It is the feed pipe TO the X head pump that has a manual control valve on the C.B. locos, NOT the pipe to the clack. Otherwise my comments above are correct about the difference between ex-works plumbing & as running in service.

I've never driven/fired or rode on a Baldwin so I'm not familiar with their cab layout as regards the position of the minor hand-wheel controls.

By coincidence all of the intact pipework photos, incl the UC San Diego source, are of the RHS driver's (engineer's) side only. The "window" has been cut into both cab sides, so I'm still inclined to think it has something to do with manual control of the boiler feed-water.

Another oddity is none of the photos show a brake operating cylinder, neither vacuum nor Westinghouse, though the leading & centre axle drivers have brake shoes.  

Regards,               Michael

My initial impression was that the small windows on the cabs had something to do with the conversion to oil burners-perhaps access to a valve or sight window?

My second theory was that the windows would allow employees to place their burritos (wrapped in foil) next to the boiler so they would be hot for lunch. I only say that because that is how I use to keep my lunch burrito warm, albeit on an internal combustion motor...
