I picked up an ABBA set of FT's (Santa Fe Cigar Bands) from a dealer on ebay a while back.  I love them.  They are quiet, smooth and have a decent amount of pull.  My only complaint about them was that the A units had a white LED for a headlight that cast the usual blue tint.  Since I was converting them all to DCC I replaced the stock LEDs with some that I cut off Digitrax decoders that wound up going into B-units.  

Getting the shells off the A-units is a bit touchy.  I wedged flat toothpicks under the sides, near the corners to slide the shell up.

I agree, Trainfreek, I think they are a notch better than Atlas and equal to or slightly better than Kato.  I say that being perfectly content with the Atlases and Katos on my roster.

I really don't want to start anything and I normally don't use the word 'wrong', but R.T. what you said in this last post is highly incorrect and could easily break things.

First off, Mailman said he had a 19V AC power pack rated at 5.5VA.  5.5VA @ 19Vac wields about 290mA!  That is 0.29A and is barely enough to run a Loco on HO.  Plus its AC whereas HO & N locos run on conventional DC (Providing its not DCC we are talking about.) 

To get that powerpack to work Mailman, you will need to run the output of that power pack through a FullWave Bridge Rectifier.  Even then though, you will have about 11.7Vdc with a maximum amp capacity of 290mA.  Unless you read the specs on it incorrectly, that power supply just isnt gonna cut it.

Second off, N scale locos draw less power which means that their motor's resistance is higher, not lower. (plus don't get confused between resistance and impedance, they aren't the same thing!)  You are correct in saying that 12V is 12V if you are talking about taking a 12VDC power pack and using it on both HO and N.  No issues there.  Just make sure it is actually a 12VDC powerpack!

Lastly, adding resistance(and/or impedance) in parallel will not increase the circuits overall resistance, but will, in fact, lower it and draw more current!  Which translates into a very hot resistor.  If you need to limit current to a device, then install a resistor in series with just that device.



I was originally going to pass this over by saying "WHATEVER!' and being done with it but when you made the assinine comment about "PLEASE DON'T GET CONFUSED BETWEEN IMPEDENCE AND RESISTANCE.  THEY AREN'T THE SAME THING" and that raised the hackles on the back of my neck.  Considering the fact that I have forgotten more about electronics than you will ever know I present to you the following conditions.

Mailman said that he has an HO POWER PACK - PACK!!! PACK!!!
Powerpacks have a set of AC terminals and a set of DC terminals, the DC terminals which are always (if NMRA compliant) 12 VDC.  The AC terminals can be almost any AC voltage and MUST be labeled on the outside, not only with the voltage but with the amperage draw.  Mailman has a POWERPACK with a set of 19VAC terminals rated at 5.5VA.

All a motor is is a coil and coils have impedance instead of resistance and in order to increase the (theoretical) resistance of an impedance device i.e. motor you must increase the (theoretical) resistance of the circuit and, because it has a motor/coil in it you must place a resistor in PARALLEL across the motor!!!!!!! An N-Scale motor does not have enough resistance/impedence to dissipate the wattage (that is what makes a motor go, by the way); try hooking an N-Scale circuit up to an HO pack sometime; any loke on the track will go from zero to 293MPH in about .0006289100456 seconds.

I have 2 FT A/B sets that see considerable time on the track.  They are as good looking and quiet as any offering from Kato or Atlas.  They operate at extremely slow speeds without cogging and pull as good as any diesel that I own.  Their full throttle speed is not excessive like Kato and older Atlas.  I have not owned any of their models that had flaws in detail, but it is my understanding that they are very quick to provide replacement shells in these cases at no cost to the customer.

 I also have quite a bit of their box cars and reefers.  These are also very nice operating units.  They compare favorably to any of the other manufacturers for quality and are reasonabley priced.

I have an Intermountain SP tunnel motor (short nose). It looks and runs beautifully, but it's the noisiest loco I have. Not much of an issue, though, I probably won't need a DCC sound decoder for that one! :)

The smoothest one I have is an Atlas Dash-840B, runs as smooth as butter.

Thats because they aren't.  Since you won't believe me, look it up for yourself.  It also was not assinine, its fact.

I site wikipedia:

 

Electrical impedance, or simply impedance, is a measure of opposition to a sinusoidal alternating electric current. The concept of electrical impedance generalizes Ohm's law to AC circuit analysis. Unlike electrical resistance, the impedance of an electric circuit can be a complex number, however, like resistance, the unit of impedance is the ohm. Oliver Heaviside coined the term "impedance" in July of 1886.

 

Link to Inductance/Reactance Definition 

 

Electrical resistance is a measure of the degree to which an object opposes the passage of an electric current. The SI unit of electrical resistance is the ohm. Its reciprocal quantity is electrical conductance measured in siemens.

The quantity of resistance in an electric circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit.

Yes, and as previously stated, 5.5VoltAmps (Apperant Power) is only good for about 300mA ish at 19Vac assuming a powerfactor of 0.8 (American standard)

I have been wrong before, but this goes against a decade of Navy training and experience.  If you are correct I would LOVE to see the reference.  I just cold resistance checked my locos motor, then added a resistor of equivilent value in parallel and remeasured the resistance.  My experiment followed parallel resistance laws perfectly as circuit resistance dropped by half, which would translate to double the current flow... exaclt opposite of what you said.  Since they are seperate branches of the circuit, other than the voltage drop due to increase load at the terminals, the resistor in parallel doesnt affect the motor windings in any way with DC power.

I say resistance because DC will be applied to the motor, not AC.  If it was AC then I would say that the motor is exhibiting Reactance, not just Impedance as Impedance is one of three components of Reactance (the others are Capacitive and Inductive).   Link

But I also understand that since the motor is not spinning, true Reactance of the motor cannot be measure as the frequency component of the Inductive Reactance is currently zero and therefore overall Reactance is not accurate as I am merely measuring the Resistive component only.

Um, I have been wrong many times in the past and freely admit when I am, but this statement just isn't true.  I did just what you suggested and ran HO and N equipment on the same Tech II and it did just what I thought it would... ran just fine.  Read over the documentation at MRC's website if you don't believe me.

Trust me, I am trying very hard to keep it civil.  I just can't stand by when advice is given that I think its incorrect/possible harmful to equipment.  As an outside party, was there anything in my original post that was offensive/unprofessional?  If so, I will edit it and take it onboard as a lesson learned for future reference.

 Oh btw, I decided to go with a small N scale layout till I get a house/basement.  Track plan to follow shortly for critique.

I have found when you give advice and it's not what the other party wants to hear no matter how right you are they will 9 times out of 10 find it offensive even when it wasn't.

I saw the Arrow on your PAs, and I thought that would make a great paint shceme for the a shortline on a pair of Switchers. I changed some colors to others and I modified the arrow I'll post the Drawing when I complete it.

Here is the End Result Twin Cities Southern MP15DC 1500

I copied the image from http://trainiax.net/mescaleloco.htm and pasted it in Paint. I filled on the colors using some of the Color codes that he has on his website, If you go to the contributed drawings and find the ones by Jay Tester those are mine. What do ya guys think?

"try hooking an N-Scale circuit up to an HO pack sometime; any loke on the track will go from zero to 293MPH in about .0006289100456 seconds."

I'm a little reluctant to get caught up in this cat fight, but that statement is just silly. I have an MRC Tech II that is an "HO" pack and I ran my N scale trains for years with it before I converted to DCC. The N scale display layout (DC powered)  I use for shows has also been running on it for the last 4 years.  BTW, I sell electronic products.

Why in the world do you think an N scale loco would suddenly leap forward at full speed if it was hooked to an  "HO" pack?  Perhaps if you cranked the throttle up all the way, there might be some potential problems, (like flying off the rail in a corner Smile [:)]) but normal operation will be no problem whatsoever.

micro-trains makes the best, but expensive rolling stock. I like Con-Cor's autoracks, walthers usually has them and they're common at train shows. I'd agree that atlas and kato are very good. May I also recommend DeLuxe innovations' cars; they make a lot of modern cars like wood chip cars, spines, and stack cars. Life-like is serviceable, and i know nothing of roundhouse, but haven't seen anything from them in a while.

Hope I could help!

So my wife and I are looking at a new house. Currently I have the entire 2 car garage for my HO scale empire. Its Green River, Wyoming 40's-50's Union Pacific so Big boys, Northerns and Challengers. are the big wheeled monsters. Well the new house I could have the formal living room for my train room. Let me list the plusses first.
#1 Inside the house with A/C Heat
#2 Flat floor no sloped garage floor
#3 No more window units
Negatives
#1 small room 12x14
So I am thinking maybe I should switch to N
Now I am unsure if there is lots of stuff available in N scale
Not newer diesels, maybe 1st generation E-Units and F-Units. Also steam of the time period.
I have about 100 pieces of rolling stock
4 or 5 buildings
300 ft. of code 83 track with 30 turnouts.
All of this can be salvaged easily actually I can even get the cork up without any damage.
I really like having 36" radius curves and running 15-20 car passenger trains and 30-40 freight runs.
Any thoughts??

thanks
