How does Bachmann keep going? From the standpoint of a guy who fixes trains:
* Parts are often available and available through their website.
* Absolutely fantastic support. Laura Harris understands your questions, reads your whole email, and replies within a few days.
* Fantastic parts department. I had a question that fit in both the parts and customer service domains, emailed parts first and they answered their part and forwarded the email to customer service so they could address it.
* Their locomotives usually run decent. You're not going to get Kato performance in every box, but you'll get something that runs every time.
* Best warranty / Service plan in the business, short of "We'll just fix it.". $25 will get even an old locomotove repaired or replaced. (See website for details.)

I'm not affiliated with Bachmann, just an extremely satisfied customer.

Fluke meters are reliable, in the statistical sense. They’re also easy to use, versatile, and durable. But they’re not cheap. I was lucky enough to buy a used one from an electronics guy who was retiring. It’s worth keeping a lookout for a used instrument.



Fluke meters are good, but their accuracy is a function of price.  Towards the low end, they work well, but only guarantee their AC accuracy to about 2kHz.  Their desktop DMMs are accurate into the 100s of kHz on AC.  I also have a Fluke 1000:1 probe at at work, you don't use that with a low end handheld. For real accuracy and less mental math you have to use that with one of their high end handhelds.


Some of the TEK desktop DMMs out there are in fact a rebadged Fluke.


For the truly cool factor (and accuracy to go with it), you want the old HP3458A.

A great buy! It’ll prove extremely useful. 

I think I paid about the same for mine. My wife’s reaction: “What do you need that for?”

What’s your layout like, Jay?

Hi Gang:

When I worked, I was a tool maker and a gage designer. When I designed a gage, getting the measurement right was important, similar to knowing your true DCC voltage. As a tool maker doing setups knowing my vise was straight was important to a certain tolerance, but this was a comparative measurement. So on a train layout knowing if the DCC voltage drops is what you are looking for, not the exact value. If it drops you can search for the problem. Similar to the engine temperature gage in your car, seldom are values shown, just too hot and too cold.

Thank you for this....I am once again gathering notes for a bridge from my Cabinets over to my Main 30" High Layout.
For now...
I plan on swinging out Two Operational Matched/Twin Bascule Bridges which together sit on one section of lumber/aluminum then (river below); then are locked into place.
Just getting the two Bascule bridges to align has been an issue..
I added a second motor and gear assembly which seems to tighten up the bridge considerably as it lowers into place. Now for the other one.

Hello Mark:

Jim and I started building these 10 years ago. The lock block went in about 9 years ago and are still serving well.

I once had a Fluke frequency counter.  It was the most reliable piece of gear I had when I used to modify CB radios to go above channel 40 and below channel 1.  I just wish I had never sold it as I would like to have it back.  I do not know about their DCC meters or even their DVM's.

Are you talking of two bascule bridges side by side that sit on the alum/lumber to 'swing out'?....swing which way?? Have you got some sort of sketch?

I have in mind twin bascule bridges side by side that will mount on my swing up to the ceiling frame. I'm looking for the 'appearance factor' so will NOT want to make the bridges operational themselves.

IMHO As a modeler, I don't need the accuracy y'all keep talking about. Any device that reads "accurately" is costly. There's no cheap alternative. My free HF meters do everything needed in model railroading. They measure DC & AC volts. Amps, but not for DCC, ohms and continuity. Also the little AA/9v battery test for more than just volts. So if y'all need more, you will have to bite the bullet and spend money. And I have successfully used these HF meters to get the info needed to make sure my layout is running. And make corrections. And I'm not here to point fingers or hurt anyone's feelings. OK, they aren't strictly free, you have to buy something at HF to get the free meter.

Yep.  I have 2 HF meters and they do all that I need.  Sure, they make better meters but ya just cannot beat free!

They are actually TWO Lionel so called O Scale Bascule Bridges (circa 1998 Chinese Construction) which are set in stanchions (Lionel Provided)
which sit end to end.
So...a Train enters one side of the Bridge...then crosses over to another.
Good Luck with that...I am still working on a precise end to end fit and alignment.
>>> In N Scale this means the two lowering bridges must have a near perfect alignment of less than 1/16th's of an inch.
----
With a bit of whittling to the underside of Dual Track Kato viaduct sections...they can snap over the existing Lionel Three Rail system.
====
With one motor however and gear set...As a single bridge lowers..it tends to skew to one side and wobble a bit.
By adding a Second Gear Motor Assembly, I hope to lower the entire bridge into tighter (less clearance) position.
*Ordered the extra set from Lionel. I will need another.
======
The Twin End to End Bridges will meet in the middle.
Over nothing below them ?
No...I was not able to extend even one bridge a few inches and allow it to rise to a straight up position - 90 degree angle...
So ...No, I am not passing by body through these two bridges.
They as is will only lift to an angle of 45 degrees...More of an affect rather than an effect on my Layout.
I intend to keep them operational by remote control of their motors.
=====
Here is where my initial inspiration came from.
http://www.foundsf.org/index.php?title=3rd_St_Bridge_Then_and_Now

The Lionel Bridge meet nearly the same exact dimensions...when using N Scale Ratios.
The Twin Bridges at 23 inches long each but not the land base ...Can expand across a 36 inch walkway.
That's why there will be two.
=====
When not swung out to connect to the main layout....They are hidden in a cabinet.
Just a Heads Up...I probably already have over 100 hours into this project including re-detailing just one of the Bridges with HO and N Scale parts.
This mixture of purchases has often confused people on exactly which scale I am primarily modeling.
But I assure you...Many items in Model Railroading are not properly sized.
I was somewhat a weird child who carried a Ruler around with him with my name on it.
I "mark" or measure near on anything and everything.
So...Near on Immediately I see N Scale in an O Scale Bridge.
:)) Mark

This is a properly sized O Scale Bridge.
https://eaglewingsironcraft.wordpress.com/tag/o-gauge-vertical-lift-bridge/

Yes taller than a man.
All Lionel Operational O Scale Bridges are more closely aligned to the measurements of N Scale at 1:152 ratio.

Re: DCC Meters

As I said. This is model railroading. Not rocket science. As for the average, normal model railroader, the cheap HF meters are sufficient to get average readings that help determine voltage loss. I measure both DC and AC volts. As long as they read the same at each end of my layout. And that means the 3 meters can all have different readings, but use one meter at one end and then the other end and if it reads the same, it's OK. Do the same with other meters to be sure. But for "accuracy", I'm not interested. I don't need "accuracy" or expensive meters. This is a hobby for fun. And y'all ruin my fun by insisting that cheap "VOM", which I take it to mean HF, aren't "good enough". Phooey! I'm not here to hurt anyone. I'm not trying to sell HF. I'm only speaking MHO from my experience. If y'all want to spend $80 or more, go ahead. As long as I'm sure my track voltage is consistent from the command station to any track on my layout, I'm happy. This is not to put anyone down. This is just my opinion and experience. Y'all make it sound like "if you don't buy $80 meters, you won't get accurate readings." So what? The time you need to buy a RRamp meter is when you like to spend money for "accuracy". But my sincere point is why? That's like buying a Cadillac instead of a Chevy. They both get you there. And what difference does it make if you get a reading of 11.6 or 15.6? As long as that reading is the same wherever you check.

Re: going from bachmann to peco

PECO is made in the U.K./British. ME is made in the U.S. But I found ME harder to work with. PECO is a quality product that IMHO is the better of what's available here in the U.S. The code 83 is pretty darn good and I like it. As for turnouts. If you don't run 0-4-0 steam engines, and/or all diesel, the Insulfrog is good. The Electrofrog is good too, but requires wiring. Of course, if you use a machine to operate the turnout, that will require wiring. And Electrofrog would be worth using. But if no machines, and you only hand throw, the Insulfrog is easier to install. I use NO wiring whatsoever on my Insulfrogs and point feed. Do check out PECO's web site. They have good info on their turnouts. Also, some YouTube videos are helpful. Go ahead and ask questions. That's what we are all here for. To help.

Rail joiners & PECO

PennsyNut
 

I have a problem with my track. I have PECO code 83 flex, Insulfrog turnouts and code 83 joiners. The joiners are giving me headaches. Not to forget split nails, cut finger tips, etc. I even try putting a joiner on a spare piece of rail to then put onto the track. But those joiners are way too tight. Filing the rails, top, bottom and top of the base - very lightly, just enough to smooth and remove any burrs. Can't seem to figure out how to spread the end of the joiner a bit, just to get it started. The darn things just don't like me. LOL Positive help requested and appreciated.

Wiring the LEDs in a DC wired loco for DCC

dennisedgar7
 

I have a DC loco that has 4 LEDs front and rear. There are two white LEDs and two red LEDs at each end.

When running forward in DC mode the two white LEDS light up and two red LEDs in the rear light up and vice versa.
I would like to install a decoder into the loco but I am not sure how to wire the LEDs so that I get the same functionality.

The LED terminals are not all visible. I fact there are only 4 leads coming from each bank of LEDs.

I am not sure how to up load a diagram to show the existing wiring layout.
Is anyone able to assist me?
