What scale and what details are you looking for J H?

using one manufacturer's product will definitely cut down on unwanted disconnection.

Jerry

How so? As long as knuckle couplers with springs are being used (in the same size category) and their heights are properly set due to the aforementioned Kadee Coupler Height Gauge, I have found no unwanted disconnections using different brand knuckle couplers with springs, together.  

Now, if you wish to talk about durability among brands, that is a different discussion entirely...

junk, a tip for knuckle couplers w/springs no matter what brand you use, put a teeny tiny drop of CA GEL glue on the spring closest to the shank; preferably bc it is easier, before installing them on the car.  This will help cut down on missing springs.

Anytime mac  .

It is meant to go on the "divergent" or curved part of the switch/turnout.  Not that you can't use it anywhere, but that is where it is meant to be used.

As long as the flex track is Code 100, yes.  You will need to put road bed (I recommend Midwest cork) under the flex track to match the height of the EZ track.  Be careful not to make the radius on the curves using the flex track, too tight. 

What kind of locos are you running?  This will influence the radius of the curves you should use.

No idea based on how you obtained them?  Usually the underside (frame) can provide some hint.

Short of identifying them that way, have the ability to post pictures of them?

I would hope they are HO, in order to run them w/your HO locomotive and on HO track. 

Rolling stock is just another term for freight cars, btw.

You are more than welcome for the help.

the cars have the old atlas horn hook couplers

Right, we got that, but what make are these cars??  In other words, who makes these cars you have?  This is important to know in order to help steer you in the right direction.  While I am asking, how old are the cars (rolling stock)?

I can change the loco Coupler with a Athearn 90601 Ho Horn Hook Coupler (X2F) and not have to change all the cars.  I know confusing, but sound right to you? here.

Not confusing at all but no, that is not the way I believe you should go about it, agreeing with reasons cited by ACY.  There are also other reasons not to, that have not yet been cited.  You have the opportunity to do some really good things here and expand your HO train modeling universe.

Beginner at this and there's a million different couplers out there.

While there are a few coupler makes and several styles out there to choose from, there are not quite million  .  As far as being a beginner, as my good friend James just recently stated, we were all there at one time.

Re: "white" LEDs-bear in mind that "Bright White" usually has a bluish hue to them.  "Warm White" more of a yellowie glow to them.  You may like that look better than Bright White.  If you ever did get hold of Bright White ones, you can get them to have a yellowie glow by dabbing a little bit of  Tamiya Clear Orange X-26 acrylic paint on them.  If you don't get it right the first time, you can wipe it off with alcohol and try again or try wiping some but not all the paint off.  You can test the color using alligator clips attached to your pack or track and to the LED and resistor.  Before you paint, you can make the LED "diffuse" by rubbing some fine grit sandpaper on the resin of the LED, if the ones you get are not diffuse.

And keep in mind, if replacing a bulb with an LED, you will need a resistor to attach to the LED + leg before powering up.  1/4 Watt ones are smaller and good for tight spaces and depending on how bright or dim you want the LED to shine, will dictate how many OHMS you will want your resistor.

Assa, what make are the cars you have that have the "old style" "horn hook" X2F couplers?

**The picture above represents only 1 style of Bachmann couplers and I don't not believe this is the style you would be best to consider using to replace the X2Fs.  The ones you many want to consider are EZ Mate Mark IIs (there are other manufacuters as well) and they look like this:

But lets get the answer to my question before going further...

Correctamundo

We can assume this is a Bachmann turnout/switch, correct?

Let me ask you Arty, what power pack do you currently have?  (assuming you have at least one)

Some of the early versions of Bachmann's square type with with the big knob and reversing switch don't have accessory terminals

These types are their newer versions.

For the sake of additional information, the ones I speak of are usually a color.  For example, brown, black, blue, yellow....Not very hard to spot the ones that have both DC and AC terminals, which if one did not know, are screws.  I hope this helps further.

You can find tons of power packs on Ebay for cheap.  For what you are looking for, train set ones by Bachmann, AHM, Tyco, Model Power and Like Like for example will be fine.  If you want to go top draw, get one made by MRC.

Do the directions specify AC or DC?  This is important. 

Regardless, the above mentioned power packs have terminals for both.  My suggestion is find one inexpensively in decent shape from Ebay.  Also, buy yourself a couple of "barrier strips", this way you don't have to connect every wire for every accessory to the pack; instead you can wire up a barrier strip from the pack and then have your leads from your accessories wired to the barrier strip.  The strip allows you to get power to multiple items.   

Nope, no "inexpensive" way to power outfit a dummy.  I would cut your losses and leave as is.  How does it roll?  What make?

HO scale is HO scale, no variances other than their comparative sizes, ie: "Grammy's Outhouse" is going to be smaller in size than "The First Federal" bank building.
