Re: caboose marker lights

Steve SANDIFER

Here is what Jim Hinds (Richmond Controls) has to say in response.

Actually, Richmond Controls targets the MODEL RAILROAD MARKET. ALL Richmond Controls circuits are designed to work with ANY form of model railroad power. DC or DCC, it doesn't matter. I can't believe that ANYONE would design a circuit of this type that can only work with either DC or DCC --- it's just voltage.

Actually, DC power is much, much more of a problem to Richmond Controls circuits than DCC is. Older DC power packs have been observed to put out 28 V peaks when lightly loaded. That quickly kills the 16 V rated capacitor in many Richmond Controls circuits. On the other hand, most boosters put out 12 V square waves for N Scale or 15 V square waves for HO scale, and these peak voltages are well below the rated input voltage. I've seen a Digitrax booster with an O Scale setting to make it put out a 20 V square wave. If you know that you have to survive 20 V, the simple solution is to use a capacitor with a higher voltage rating. Richmond Controls has two modules (EZ08 and EZ09) designed just for this purpose. But it would waste too much performance capability to simply use a 25 V capacitor in everything. And that wouldn't prevent problems when 28 V peaks are coming along.

Some Richmond Controls modules have an input voltage limit of 16 V, which is above the track voltage seen with the more popular boosters. The reason for this limit is that the input filter capacitor specifications require a compromise between voltage and capacitance. I typically use a wonderful 150 microfarad capacitor rated at 16 V. The next available option is 47 microfarads at 25 V. In my experience, the high capacitance is more useful than another 9 volts of voltage rating that isn't really used. When a tantalum capacitor is taken a volt or two above its voltage rating, it typically forms an internal short circuit. This is actually very handy in a Richmond Controls circuit. The short allows excessive current through the input diode, which then quickly open-circuits internally, acting as a fuse. This protects the more sensitive and expensive components downstream of the capacitor, and it is really easy for me to replace the capacitor and diode (which I do for free).

But for systems applying more than 16 V on the rails, there are easy solutions if the user is aware what voltage he or she actually has.

One thing that very few people realize is that ALL DC permanent magnet motors have arcing between the motor brushes and the commutator. When the motor is turning due to applied power, you can look in there and see it. And you will notice that it becomes much brighter as the voltage is increased. This arcing causes microscopic burning and pitting of the commutator.

The higher the voltage, the more serious the burning caused by this arcing becomes. Having a pulse-width modulated input power source, like DCC or Aristocraft DC, doesn't help much --- the voltage during the pulse is the PEAK voltage. If anyone asked my advice, I'd strongly encourage them the steer clear of any system, DC or DCC, that puts more than 15 V PEAK on the rails. This is why many well-informed HO Scalers use the N Scale (12 V) setting on their booster when the booster gives them that option.

Any supercap circuit can be used with any load, either LEDs or lamps or something else. But the design problem is a combination of charging the supercap quickly without tripping out a booster, and then drawing current from the supercap through its appreciable internal resistance while expecting to have much voltage left over at the external terminals. That internal resistance and lamp currents tend to work against each other, but low LED currents don't cause much in the way of voltage drops in the supercap's internal resistance.

Supercap circuits are ideal for driving LEDs used to create marker lamps.

Hi all,

Claus - I'm working on a different circuit that is still based upon using
a super cap ... that can be used for either LEDs or bulbs - at the same
time. "Watch this space."

George - I don't even know what circuit Richmond sells. I've used
their products in the past and they work just fine ... but they tend to
target the DC market ... and the last time I checked they were very
"proud" of them. It was the available circuits such as those from

I am in DCC and Richmond Controls circuits work just fine. I know his locomotive circuits seem to be DC oriented but caboose and passenger car circuits work well for either.

Van Dyke worked for Standard Oil in a variety of assignments relating to both refineries and tank cars. He had patents on the frameless (Class V) and center sill with tank held in the center anchor (Class X) as well as internal heating coils for UTL before moving on to Atlantic Refining in Philadelphia. He retired as CEO of Atlantic in the 30’s.

ACF developed its own version of the center anchor in response to UTL’s design.

Craig,

Another good source is The Pennsy in Chicago, by Ed Deruin. Ed's book obviously focuses on the PRR, and is not WWII specific, but it does give an idea of how the railroad around Chicago interacted. The PRRT&HS obtained the remaining copies after Ed passed away and they are available at http://www.prrths.com/estore/index_books.html

Craig,

A great photo source is the Jack Delano collection from the office of war information at the Library of Congress. He started his 1943 RR trip in Chicago and there are many images of STMFC and CNW and Santa Fe motive power for same. There are Santa Fe track charts from the early 50s available (it didn't change TOO much) and I think some of those small eastern roads may have info available through their historical societies. I believe that NARA (national archives) has some local holdings that may be of interest from the office of defense transportation. The San Bruno branch helped me with info on the Bay area. I'm sure there are a lot of other sources, but I model a year later and 3000 miles west.

That said, Santa Fe did interchange a lot of LCL traffic to the Erie for points east as they did many reefer blocks. Other goodjCalifornia sources for me that may have Illinois equivalents were the State Archives for RR commission reports and valuation maps, the State Library for published works you didn't know existed. and the state RR museum.

Good Luck

John

Re: seasonal coal traffic

Tom in Texas

#137459

After seeing Dennis' comment about lake coal for the Port Washington power plant, I asked my brother who lives nearby what he remembered

I can verify that the old Port Washington power plant took all of their coal from boats sailing on Lake Michigan.  They would typically anchor outside the harbor mouth and bring the boats in at dusk (that way they avoided all of us salmon fishermen who would be out from dawn until the afternoon).

They'd unload the coal and then they had two big bulldozers that would push it up into big "hills" right by the shore just east of the plant.  The problem was that if there was even the slightest breeze from the south, the boats in the marina -- including mine -- would be covered with coal dust.  It was a real pain to clean off, especially getting it out of the canvas.

Not a problem anymore, however.  The utility converted the plant from coal to natural gas a few years ago.  As Paul Harvey would say, "And that is the rest of the story . . . "  :>)

"Were Head blocks outlawed ?"

"With my collection of AAR Interchange Rules the best I can say is possibly as early as 1 Jan 38 but definitely by 1 Jan 43 tank cars having head block anchorage were prohibited in interchange."

Thanks Bill,

There was an extension to at least January 1, 1939. The Mechanical Division of the AAR did not hold their annual meeting in 1938, and the Arbitration Committee's special report (1938) within the 1939 Proceedings contains no mention of an extension, but there may have been one (via supplement) as such events were not always included within the annual reports.

As of January 1, 1941, tank cars which were equipped with head blocks were absolutely prohibited in interchange. Therefore, the final date is either January 1, 1939 or there may be and extension (up to) January 1, 1941.

I am confident that Gene Green will nail down the exact date when he has a minute to check his collection.

Hi Jim,

Thanks. Nice to see a successful application of a super-capacitor. I tried using these super-capacitors before, and found their high internal resistance to be an issue. In my case, I was using two Miniatronics light bulbs that required 60ma (30ma each), a much higher current draw than your LED approach would use.

I went through my 1925 “Tank Car Manual” and they are okay then but if the head shows “distress” it tells how to reinforce. Maybe my 1934 Tank Car Manual will shed more light when I get a chance to read in detail…I think the print got finer

With my collection of AAR Interchange Rules the best I can say is possibly as early as 1 Jan 38 but definitely by 1 Jan 43 tank cars having head block anchorage were prohibited in interchange. Too many gaps in my collection to nail it down completely. We need Guy or Gene to jump in here.

Thanks for all the recommendations. Lots of interesting options there.

Besides the size difference (which to makes the EZ-41 N-scale module more attractive for my HO cabeese) is there any other reason why one should prefer the Richmond Controls EZ-31 HO caboose module for HO equipment? <http://www.richmondcontrols.com/>

Nice ... micro-size, nearly invisible, LED's now available can
be used for class lights and step lights too, they are that small!
We're going to need more DCC functions ! :-)
