I think Mike Confalone uses them manually on the Allagash Railway. They have good electrical connection. Just a flip of the finger in his videos.

I don't necessarily trust the springs to maintain alignment, but the way these are made you don't really need them for electrical contact.  The electrical path comes through the joiner from the closure rail, and any contact you get from the stock rail is a bonus.  It's easy enough to jumper around the joiner if need be.

Tore, it seems that newer ME turnouts including the HOn3, has jumper wires soldered to the turnouts moving parts, see the comments on this page:

If your enginges can handle dead frogs, then you might get along without bullfrogs etc, if not you might use Frog Juicers or microswtiches with small arms.

At least that is what I plan for my ME HO scale turnouts.

I am quite sure Mike uses nothing but the built in spring. As Knut says ""if your engines can handle dead frogs". not a problem for Mike who runs engines in multiple units with all wheel pickup, but could be an issue with NG steam.

Had bad experience with ME. They refused to honor their warranty on a switch. So I use only Peco (all manual) and love them. Jumpers across the closing rails and frog rails to an electrical switch for DCC polarity and works great. ME failed too many times.

The original ME turnouts in HO standard gauge were problematic (they have live frogs and metal throwbars soldered between the points, so are easy to distinguish).  They suffered from quality control and durability issues.  I couldn't recommend those to anyone.  More recently, the product has been improved, and I've had no trouble with the current production DCC-friendly turnouts.  I have no experience with their customer service or warranties, so I can't speak to that.

I use both ME and Peco turnouts, and use a skewer to throw them over.

I've had no issues with the majority of my diesel loco's, although as Ray said, they are not NG steam.

The Blackstone Models locomotives I will be using are excellent runners with pickup on all wheels, so dead frogs shouldn't pose a great problem. But the idea of using a frog juicer is good! I've seen that product advertised several times, but I've never really thought about what it actually does After a quick "googleing" I think that might be a great solution for me!

Tore, 

I have one frogjuicer powering two Atlas #8 turnouts. They work like a charm. If you ever are on the other side of the fjord, you are welcome to see them in action :)

"I'm just about ready to start laying track on my new H0n3-layout, and I've chosen to use Micro Engineering turnouts. My initial plan was to use Bullfrog turnout controls, but I think the control rod is a little bit flimsy, and I also need to cut a lot of holes to recess these into the fascia, resulting in a "messy" look."

  I haven't tried their HOn3 turnouts but I have some of the N scale versions and they work ok, a little harder to install since they need a frog wire soldered to the bottom of the frog where Atlas has a little frog wire tab.  I use Blue point controllers and find they are sturdy and work quite well without fascia knobs, I just reach under the layout and throw them directly. As for customer service I'd had great experience with Micro engineering.  A few pieces of my code 55 flextrack had some random spikes missing and they sent replacements after I called to ask about the issue......DaveB
