Some of the sections that tabs are made from are bulb angle, unequal
angle or channel. The flange (short side of the "L") is cut square while
the web or the surface we see is cut at an angle. Tabs made of channel
have two flanges cut square and the web cut at an angle between those two
square cut flanges resulting in the steps we see. Tabs made from angles
have only one square cut flange and it is up against the side sill and
very hard to see in photos. The side we see is simply cut at an angle, no
step.

I hope this makes some sort of sense, I always have trouble describing
something without using my hands....

Isn't that "step" just where the tab is bent into an "L" shape,
i.e. aren't we looking at the bottom of the "L" edge-on? If so,
maybe the "stepless" tabs were trimmed differently, so when they
were folded (bent into an L) the taper appears to be continuous.

I have posted a photo showing a CB&Q tank car oiling tracks west of Chicago to keep down the dust. The photo has been copied from the Railway Age Gazette of September 1911.

A horizontal perforated pipe has been attached to the bottom outlet of the car to distribute the oil "which is heated by steam from the engine", but with baffles to prevent it being sprayed on the rail, and the flow rate is controlled by a lever attached to the outlet valve.

Can anyone give me some clues about the car?

Mont Switzer states (MM 12/91 p 58) that CIL 9150-9499 had National Type B-1 trucks. Some published photos:

You don't need to raise & lower the nylon line, they'll bend well enough.
I've taken some light test fishing line (the only reason I've been in a
sporting goods store for years) and put a small bit into a tie, just taller
than axle height. One will hold a couple of cars nicely, although these
are not steep grades. They're also really hard to see, so they're
definitely not intrusive.

The main place I have them is at a freight house, so I have them set at the
right place for each door.

Denny, a 1 oz load is about 1/2 the typical load of a freight
car. There are also rolling dynamics involved. And under load,
the shape of the bearing and journal, and the materials, makes
a big difference. Kato ASF A-3 trucks for example roll incredibly
well without a load, but as the load increases, the performance
is affected -- it's almost a straight-line correlation.

I roll test every car that I put together, or make ready for
operation. It takes a little time, maybe 20 minutes, to identify
the proper truck design for that model and then find a model truck
and wheelset combination that gives good results. It's makes no
difference to me how well a truck rolls "in theory".

For example, remember those old Lindbergh trucks? Those things
rolled like crazy, we thought they were miraculous in the 1960's.
Oh wait, until you put a car on them. Then your results may vary.

Tim O'Connor

Tim O'C inquires about the effect of weight on truck rolling test data.

I do not routinely test truck rollability with/without weights, although I do so on occasion. My reason for not doing so is that I use the test data to conveniently guide my choices of wheel sets going forward (not excluding leaving OEM alone!) without having to parse out with testing anew with each install the usual small inherent differences resulting from both variable weighting, but also rollability differences caused by the common variability between nominally-identical trucks. Sometimes the weight improves rollability, occasionally in dramatic fashion; while at other times, the same weight can all but stop a truck dead in its tracks. Most of the time, in real time, it makes no difference.

As to the new Kadee trucks, I did indeed test the Barber S3 with and without weight. The weight (a 1-oz. lead block balanced on the truck bolster) caused the rollability to improve, but ever so slightly- remaining still in the midst of the Acceptable/Good field. This was why it was not mentioned.

Aren't free rolling trucks somewhat of a two-edged sword?

Wouldn't any track where a freight car might be parked have to be perfectly level in order to avoid having the car roll away?

I know about putting a twin-coil switch machine under the track to raise and lower a nylon hairbrush bristle to keep a car in place. Are there other methods?
