Re: Eames Brake system
The Eames vacuum brake only had one pipe which ran end to end.
Vacuum brake hoses were somewhat larger and heavier than air brake hoses. The vacuum brake's actuating pistons (which look like a short, squat ice cream cone) were mounted in the trucks with linkage to apply the brake in each one. Hose connections were on the vacuum line for each truck's brake. Reservoirs and valves with their related piping were not needed in this system. The underbody of a vacuum braked car was empty-looking, compared to an air brake equipped car. The car's hand brake was linked to one of the trucks. Attached is a drawing of an Eames vacuum brake piston, and a builder's photo of a car built with the Eames vacuum brake. Although it's a passenger car, a freight car would have the same piping arrangement. Ed Bommer

Eames Brake system
Larry Smith
I'm building seeral freight cars from the PRR narrow gauge lines. All of them were equipped with the Eames vacuum brake system. I have found one diagram showing the piping under the car but it is only at the truck end. Does any have or can tell where I can find a diagram showing the piping arrangement under the cars.

Re: Handbrakes
Dennis I'd really like to see the reduction gearing you're describing. I've never seen an example of that. They used a pawl and ratchet but that's not a gear box - it gives no mechanical leverage. Tim O'

Re: Photo: Santa Fe Gondola
Charlie, what type of end do you mean? Drop ends? There were certainly more classes of Santa Fe gondolas with drop ends, than just two. At first I thought it could be a Ga-103 but I wondered if the plain bearing trucks would have been applied in 1958 to a brand new mill gondola. The only photo I have of one shows roller bearing trucks. Tim O'Connor

Re: Janney couplers full and 3/4 size
Schuyler Larrabee
Could you explain what the SAM “safety link & pin” coupler is/was?
Schuyler
From: main@RealSTMFC.groups.io <main@RealSTMFC.groups.io> On Behalf Of Randy Hees
As you suggested, most (all?) California and Nevada narrow gauge lines used 3/4 size knuckle couplers (if they used knuckles). The exception being the NCO, which purchased used cars from the F&CC which came with full size (size D) couplers. For a short period of time the NCO converted one end of the "new" cars to 3/4 size and ran them in pairs. The Pacific Coast Ry used 3/4 size.

Hello, Milwaukee Road stock cars built in 1929, have the same appearing hand brake. The car diagram page states it is a Klassing Hand brake. Ted Schnepf 126 Will Scarlet, Elgin, Ill. 60120 847=697-5353

But the point is, it's obvious, with that large gear housing at the eave line, it won't be mistaken for the old time 'stem winders'. It also uses a chain, rod and bell crank rather than a simple brake staff. My point was a reasonable number of vertical staff hand brakes also used reduction gearing, but the gearing was almost hid under the end sill. Dennis Storzek

Re: Handbrakes

The C&O also had a similar geared brake design, an example can be found on Erie 1932 boxcars also w/square brake staff.

Re: Photo: Santa Fe Gondola
If the 1950 date is only slightly off, this could be a builder photo of a Ga-76 mill gondola built in 1951. These were the first ATSF 65 foot mill gondolas built at Topeka. Tim O'Connor

I'm a little late to the show but at one time (1940s?) a man with a name something like Wisswasser offered O scale drawings of many RDG cars. I bought several in the '80s or '90s through the RDG society. |

As a reminder to some of our list members, geared (or "power") handbrakes does NOT mean exclusively horizontal shaft/vertical wheel handbrakes. Many vertical shaft/horizontal wheel installations had gearing to assist the brakeman in applying the brakes and would therefore have been considered "allowed" under these rules.Yes, they were quite wide spread and hard to spot, since unlike Bob Chaparro's example which had the reduction gearing up at the roof eave, most examples brought the brake staff all the way down to the end sill, and tucked the reduction gearing beneath the sill. Anexample would be the CP "mini box" recently discussed: http://lists.railfan.net/erielackphoto.cgi?erielack-06-28-19/X7177.jpg I've also found similar gear on a 1926 Soo Line box: And also on the Soo's 1936 copies of the 1932 ARA car: Note this later car also has a square brake staff.

Re: Photo: Santa Fe Gondola

Assuming that is a Santa Fe gondola, it would be either a Ga-91 class car numbered 168400-168549 built in 1955 by Santa Fe or a Ga-103 class car numbered 168150-168399 also built be Santa Fe in 1958. It would be nice if there was a car number for the car. Those
are the only two classes of mill gondolas with that type of ends.

The end view appears to show the narrow width characteristic of 65' mill gons, such as the Ga-70.

I find it interesting that the “ATSF" and number were sprayed onto the steel diagonal braces. That seems very unusual, and I don’t recall seeing that before: the reporting marks were always on the siding alone and never on the bracing.
