The gears and motors are between the wheels. If one is not really sloppy, especially with the exterior journal boxes, there is no reason for grease and oil to penetrate the leaf springs. I do speak from experience as a youngster with Third Avenue Transit and their universal use of Brill-design-and-parts (lightweights) and Brill-manufactured (convertibles and about half the second-hand cars) trucks. Later, Third Avenue Lightweight 629 and Connecticut 2350 Birney at Branford.
They and we did not oil or grease the leaf-springs deliberately, to the best of my memory.
Note that my 'into the toilet' comment strictly applies only to pitch and yaw compliance, not vertical riding. Any properly-designed car should 'ride' better when loaded (provided it isn't physically 'bottoming out' on the springs) just as trucks or some buses do.
The issue with leaf springs is that their 'damping' is mostly friction, and if you grease or oil the leaves to reduce wear and noise, physical damping especially for larger moments can become very slight compared to oscillation, often resonant...
Russ's reply, his capitalization bid difficult to remove:
AS FOR RAILROAD 4-WHEELERS, THAT IS OF COURSE TRUE. RODE THE ENGLISH ONE ON THE PAOLI LINE DOWNHILL AT 70 MPH. WELL-DESIGNED SUSPENSION.Birneys are laughably lacking in anything like damping, and most have an almost ridiculous longitudinal polar moment of inertia. It should not surprise anyone, with or without formal engineering training, that they ride and often guide poorly.
ALL (IT THINK) STREET/INTERURBAN CARS PRIOR TO PCCS USED LEAF SPRINGS AS A DAMPING METHOD. A PRIME EXAMPLE IS THE FLEET OF PITTSBURGH "LOW FLOOR" CARS WHICH HAD FLEXIBLE TRUCK FRAMES TO ACHIEVE EQUALIZATION AND HAD ONLY A LEAF SPRING BOLSTER ARRANGEMENT. THE PCC B-3 TRUCK IS FUNCTIONALLY THE SAME, BUT BY USING COIL SPRINGS HAD TO HAVE HYDRAULIC OR FRICTION DAMPERS. THE B-2 TRUCK WAS DESIGNED TO HAVE DAMPERS AT EACH AXLE. THE BROOKLYN CARS HAD DAMPERS AS RECEIVED. YOU MAY RECALL THAT BOSTON AND TRC CAME UP WITH A FRICTION DAMPER FOR APPLICATION TO B-2 TRUCKS. Street railways, as far as I know, have never been known for maintaining precise track geometry, or for that matter rail condition.A Birney encountering rail corrugation, for example, is not going to demonstrate serene Citroen-like compliance.
NOT SO FOR PAVED TRACK. STREET RAILWAY PAVED TRACK IS A VERY PRECISE CONSTRUCTION, WITH GAUGE PLAY TYPICALLY ABOUT 1/4 INCH. RAILROAD PEOPLE WHO GET INVOLVED WITH STREETCAR TRACK USUALLY SCREW THINGS UP. SIGNIFICANT VERTICAL MISALIGNMENT FOR PAVED TRACK TYPICALLY ONLY OCCURS WHEN THERE IS A BROKEN JOINT. OPEN TRACK IS SUSCEPTIBLE TO ALL THE VERTICAL AND HORIZONTAL MISALIGNMENTS AS OCCUR ON RAILROADS. RUNNING A BIRNEY - OR MOST ANY 4-WHEEL PRE-PCC STREETCAR - ON POORLY MAINTAINED OR LIFE-EXPIRED TRACK IS NOT GOING TO PROVIDE A GREAT RIDE.
DOUBLE-TRUCKED CARS WITH A SWING-LINK BOLSTER ALWAYS HAD A PROBLEM IN THAT THERE WAS INSUFFICIENT DAMPING OF LATERAL MOTION. PCC TRUCKS HAD PROVISIONS FOR APPLYING LATERAL DAMPERS.
TRUCK SUSPENSIONS SHOULD BE SUCH AS TO NOT COUPLE TRUCK PITCH OR SIDE TO SIDE CHANGES IN ELEVATION TO THE CAR BODY. AIR SPRINGS CAN DO THIS WELL, USING. LEVELING VALVES TO DEAL WITH STATIC CONDITIONS.Actually load them to capacity for revenue, and the situation rapidly goes farther into the toilet. NOT WORTHY OF COMMENT. (DLK: My oWn expErience wiTh Co9nnecticut 2350 at Shore Line Trollet Museum (Branford) is that riding, never bad on the well-maintaiuned trasck, actually improves with loading..
I'll pass on your reply to him...
Russ evidently does not comprehend the amount of work that had to be done by Alan Wickens, Waggon Union, and others to get four-wheel rail vehicles to ride stably at higher speeds. See the general subject of "Pacers" for a quite reasonable counterexample.

Please be careful, Dave. Praying for your safety.
Comment from Russ Johnson:
Need an expkaitionh for that.
But hereis Third Avene's last Birneym converted to rai8l-grinder and slot-coleaner:
If you are reviving low-floor Birneys you can get a LOT closer to true low-walkover at the ends by re-adopting the Lindall articulation scheme...

More Birney pictures:
When the H streetcar line, than ran from the New Haven's Harlem Shuttle's station on the NYNH&H line to Oak Point Yard and the H. G. Bridge, west to the line to GCT, was repaced by bus in 1937(?), it was a special occasion, since it ran by Fontain Fox's home, and he was the cartoonist of the Tunerville Trolley comic strip. Regular double-truck convertables had been the regular equipment for many years. But the Third Avenue people borrowed one of the Birney's leased to Stienway to take part in the final run, with Mr. Fox, since its diminutive size made it a stand-in for the comic strip's car.
At the time there were interconnecting tracks for the move each way, but the car had to be towed while on conduit-only tracks beetween 59th and 129th Streets on 3rd Avenue.
And it seems as if the rest of the thread has now been removed?
This was supposed to be on the General Forum on the Billy Graham thread. How it came to migrate to this threade is a very good question. What was supposed to be here is an invitation to anyone who wants the pdf versioni of the Cox Birney book that I preapred with the pages on this thread, just email me at daveklepper@yahoo.com, and the pdf will be sent as an attachment to the return. Of course no charge. I am sure this is what Harold Cox wanted, because he made all pages available for free on the internet.
Charlie Hebo: WAs simiply trying to prove how train travel made possible better service for my clients because of the ability to carry sensitive equipment with me instead of having to check it (or buy a second seat for the equipment?).
Anyone wishing to have a pdf of the complete book can email me at
daveklepper@yahoo.com
And I will attach the pdf to my reply. Of course no charge.
I will be fulfilling Harod Cox's wishes in doing this.
The last passenger operatoin of Birneys in New York City, which at one time did have them providing sevice on lighter lines in Brooklyn and The Bronx, was on Steinway Lines in Queens, Birneys leased from Third Avenue Railways were used, painted in TARS cram-yellow and red, but labeled Steinway Lines.
Great. Thanks for posting

I tried to sell my two cents worth, but no one would give me a plug nickel for it.
I don't have a leg to stand on.
A Fort Smith, AK, Birney can be viewed at the website of the Fort Smith Trolley Musuem. When I try to post the picture, it dissapears.
Particularly greatful for the picture of 102. This may have originally been built for left-hand operation and remodeled for right-hand.
Do not know anything specific about Levis car #83 but here is the 3 picture set from the "collection"

I have some doubts that car 83 was in revenue passenger-carrying service in Levis in August 1944. The date may be the date the photo was printed, or 83 had special duties.
But thanks for the photo, and it is interesting to see what Birneys may have replaced. Even though Levis converted to bus in 1947, it had bought three Birneys from Montreal in 1945!

Again, I urge others to post Birney pictures.
The Bezek server is giving me problems in trying to edit the previous post. Because of a specific health problem, I have not been able to take my laptop to the University yesterday or today. When I can do so, possibly tomorrow, Tuesday, I will edit the previous post, and any other posting of mine that requires editing, post the picture of the San Antonia Birney, and probably some other pix as well.
Am able to edit today, found the pix had been posted but just did not show up with the narrow-band server. And here is a still improved photo of the Halifax Birney, with a comment to follow:
From Wikapedia: Historically, the Halifax Peninsula had an extensive streetcar transit system dating to the late 1800s. Operated by various private companies including the "Halifax Street Railway Co.", the "Nova Scotia Power Co." (not the same company as the present electric utility), the "Halifax Electric Tramway Co.", the "Nova Scotia Tramways and Power Co.", and the " Nova Scotia Light and Power Company, Limited", the streetcar system was abandoned by NSL&P on March 26, 1949. Streetcars were replaced by an electric trolley coach system, however, the last electric trolley coaches were replaced by conventional diesel buses on January 1, 1970 operated by the Halifax Transit Corporation. Halifax became an all-Birney operation. See page 92.
Nice job David! I'm sure that grey pavement is closer to the mark than the red in the original photo.
[quote user="Firelock76"]
David, somehow I doubt in that Halifax shot the pavement is that reddish color. What we're seeing could be due to color shift in an old slide depending on the quality of the film used. It looks like red clay or even brick dust which I doubt Halifax used for paving material, those Halifax winters would have destroyed it in no time at all.
