One consideration in frequency selection could be RFI. A good square wave can generate a lot of harmonics and model train tracks can make a great antenna. Mark
Correct. Capacitors are frequently added to the locomotives themselves for RFI (Radio Frequency Interference) certification.
Another point to consider: So far you are talking about the circuitry that attaches to the rails. The locomotive may have additional circuitry between the rails and the motor that will change how a waveform looks before it goes to the motor. So this quest for some level of perfection on one end of the equation may be irrelevant if you do not have the other side of the equation in mind.
While it is fun to tinker with the electronics - I should know, I have scratch built several throttles and even scratch built a DCC decoder! - the one element that has contributed most to good operation of Z scale is dirt. Keep you tracks clean. Wipe them with a good cloth. But also do not forget that when dealing with pulse power, dirt will also collect on the wheels of your locomotive (and rolling stock) so clean the wheels too.
Rob How is it being shipped from Galactic Headquarters? UPS,FEDEX,or PONY EXPRESS !!! That gives us an idea of 1 to 3 days ,3 to 5 , or 1 to 2 weeks depends if horses are changed out on the trip from headquarters. P.S. Rob had to bust your chops.
All I know is the FedEx guy was humming the theme to Star Wars as he picked up 10 big boxes...

No worries at all - thanks for asking - I admit it is a bit confusing.
This is a hard subject, as I am a HUGE supporter of free speech. On the whole we all prefer a good freewheeling discussion. I'm just trying to prevent it from turning into a typical Cable News show with everyone just yelling at each other simultaneously!

Is this necessary? is this the part where we measure our "fingers" to see who's is longer? None of our cars are just side slide changes btw...all stand alone tooling. But these numbers don't speak the whole truth. Sure you have 55 products...we have 36 by your count, then you have to add in 30 different pieces of track, 5 coupler combos and trucks and 58 structure kits so the actual count is 55-124. we win Ahem! LOL
Necessary? Heck no! Just intended as a way to have a bit of fun. We are all rightfully proud of what we have worked on and accomplished. And I learned something: each of the MTL box cars are separate tooling. Cool by me!
My point was simply that Z scale has grown to the point where enthusiasts of the scale are not beholden to any one manufacturer. That's a good and healthy thing. Furthermore, I'm glad that MTL makes great products at a reasonable price. It helps build the scale, and that helps everyone.
I'm also glad to see Joe posting here. He is a good guy, valuable resource, and wonderful advocate for Z scale. We may have the AZL logo at the top of the page, but we always intended this forum to be a place where everyone who is associated with Z scale would feel welcome. Got news about MTL, Marklin, or any Z manufacture? Feel free to post it here. We will advocate for our brand, but we also welcome anyone else who wants to advocate for their own Z products too!
Last, joe beat me fair and square on the product count. And yes, I do have small fingers.

A few observations regarding this conversation:
1) With regard to electricity: Z scale Is just as delicate as N scale. Z scale is also just as strong as N scale. Electrons know no scale. All of the same tricks and techniques used in N scale will also work in Z scale. All of the locomotives we have made in the past 5 years are 100% compatible with N scale electronics, voltages, and settings. 2) alberich seems to be working on a small to medium size layout with D.C. Power and less than 10 locomotives. This is wonderful as it is a great way to experiment with Z scale and get addicted. Much of the advice regarding short circuits and capacitive discharge equipment really applies to much larger DCC layouts with 10 or more locomotives running in hidden sections. These larger layouts (like mine!) have locations where derailments can happen - almost exclusively on turnouts - that cause a short circuit, and yet they are not noticed for several *minutes* yet the DCC power does not trip off, leading to burn out decoders or melted locomotive wheel sets. This is a very very different environment than alberich plans. 3) our locomotives are designed to withstand short circuits of several seconds under DC power without a problem or damage. Certainly long enough for an operator To turn off the power pack or remove the derailed locomotive. This makes perfect sense,as it is the way that the vast majority of our customers run their trains. If it were not true we would have burnt out locomotives being returned to us under warranty all the time. We do not. 4) may I suggest you start with a simple solution like a 12 volt automotive light bulb? I think you will be more than happy with that elegant and easy solution. Beside, we are all Edgar to hear your tales of layout construction, and I think more than enough time and energy has gone into the electronics department! ;-)
Good one Shamoo The ES44 baited hook. All April fools to the side . I was hoping to see them in April release. Or at least a tease. Hans said take delivery around April . I guess that was his April fools .
Not April Fools Joke: ES44 release date slipped about 30 days from the last update: currently looks like end of May.
Putting the Viewliner trucks on the Amfleet cars would be incorrect so far as the model's fidelity to the prototype. Same thing with the MTL trucks. If those types of things don't matter to you that's great, but AZL probably couldn't commercially release something like that without getting roasted and likely affecting sales.
...and Amtrak would not have allowed it under our licensing agreement.
As I said in the other thread about these wheels, even though they don't roll well, it's probably not a huge deal in the grand scheme of things. While it's not the rolling characteristics many of us expect, it is the reality of trying to represent that particular style of inside bearing truck in miniature. (and not just in Z) I'm not saying there aren't improvements that can be made...your post is a great example of that. Regardless, even as-is the P42 should still be able to drag a handful of them around a layout.
We tested 10 Amfleet cars behind a P42 as that seemed to be about the longest typical Amfleet configuration in normal service.
