I discovered a problem today. I was just about to install my first ME code 83 turnout. I have some wheels that I always use to test my track. But the wheels climb over the turnout at the red arrow and nearly derail. I can’t remember where I got these wheels so I tested a BN beer car instead http://www.railshop.net/product_reviews_info.php?products_id=50&reviews_id=2&osCsid=5ffb614ed2d6c8210b81e5fcb9c942b2 and that car also climb over the turnout. Another car from Kadee took the turnout very smooth. Can someone pleae tell me what is going on. I have around 35 locos and several hundred cars. It’s not that hard to buy new trucks for the cars that will not run but what if a loco do not run? This feels like a big problem and I do not want to continue building until I know why this is happening. 
I would use a track gauge to check the clearances and gauge of the turnout, and also one to check that the wheels you are using to test the turnout are in correct gauge. Regardless of the turnout, if you have some cars that clear the frog ok but others that don’t, sounds like you have some wheel gauge issues one way or another. Jamie
You need to get a track and wheel gauge and check to make sure everything is in proper gauge.

Here is a list of all the specs.
I own a track and wheel gauge but it never crossed my mind to use it, yes I know I’m stupid 
I will test this as soon as possible and come back with an answer.
Hi, I havn’t heard of any problems with the ME switches, this is new for me. Where I go for op sessions(2 diff places) they layout owners both have ME track and switches in code 83 and 70, there are absolutely no problems at all for op sessions on any switches. At one location we run everything from early GPs to modern ES44s and no problems at all. The other location, we operate '70s '80s with no problems either. I have started buying ME code 83 and 70 track and switches for my future layout.
Wheels/track out of gauge sounds about right. I am going to my friends place this evening for some freight car weathering(he has the tools for this) and I will ask him if their were any problems when he first laid his ME switches.

I can’t tell you how many wheels on even relatively high end rolling stock was out of gauge when checked. EVERY SINGLE WHEELSET that ‘bounced’ over supposedly ‘junky’ Atlas Code 83 turnouts was out of gauge per the NMRA standards gauge. On those where the axle length was correct, I used Proto2000 wheelsets as replacements. Many many packs of these and I never found a single one that was out of gauge when checked.
Check both, but I bet it’s the wheels, assuming there’s no plastic flash or debris in the frog flangeway of the turnout. It’s a mass prduced item, certainly one may slip by that’s just a little off, so checkign is important, but when some or most cars work fine and a few derail, it’s more likely those cars that have the problem then the track.

Ummm…It’s not meant to be a paper weight…[D)][(-D](just fooling around)

YOU NEED TO CHECK both the turnout and offending wheelsets with an NMRA gage.

There is no switch made that some.car won’'t like. It’s called MANUFACTURING “tolerances”.(No two product’s are EXACTLY alike.).
If most cars make it through the frog, it’s probably the car. .If multiple cars foull up at the same spot, look to your switch.
Cause could be truck alignment - vertical or horizontal. What happens . running the car by it’self, slooowly"?
CORRECTIONS are (a) replace the switch (b) replace the trucks (c) Find & solve the problem, yourself…,
PROBLEM SOLVED!!! This is what I did. I checked the wheels against my gauge and they where at least 1 mm out of gauge. I started to wonder why… I’m building Big Ten Curves at the moment and this is a very long grade. Sometimes I let the wheels run by themselves down the grade to check the track. Sometimes they fall to the floor, and that’s where they will be out of gauge. So I corrected them against the gauge. And tried to run them through the turnout again. Very smoooooooooooth I also checked the BN beer car and the wheels was out of gauge.
I also had problems with several ME code 83 #6 turnouts. I found that the guard rails on either side of the frog were a little tight causing shorter wheel base locomotives to climb onto the guard rail and stop ( DCC operations). I filed a little material off the inside of the frog guard rails and solved the problem. I also noticed that the points did not close up tight on several of my ME code 83 turnouts. This was a little more complicated to correct but was solved by gringing away some of the base of the stock rail under the points. I think that the ME turnouts look the best of any I have seen- short of handlaid track.
Wonder when Micro Engineering is going to build some more turnoutsfor us to buy. They must be losing money hand over fist by their lack of production. I need about 25 more myself.

ME has informed our LHS here in Texas to expect delivery of turnouts within 5-7 days, if not sooner…
Now if Walthers/Shinohara would get off their butts, life would be good!
