Kato Unitrack Crossover
« on: July 24, 2011, 03:38:18 PM »
I am having trouble with one half of a crossover. What happens is that the engines slow or stop when crossing at low speeds at full speed they pass through ok. I have power on all four ends.  All the rails are clean and level.  I am unable to see anything wrong. Any help and guidance would be appreciated. ???

It could be that your locos don't have all wheel pick-ups and they are stalling on the plastic frog.
Another possibility is that the switch on the bottom of the crossover needs switching.

Thanks for your reply, I have checked the voltage etc and all is ok.  I have not seen a switch on the bottom of the crossover (will take another look).  Straight through engines of any size there is no problem.  It seems that when crossing it is almost like putting the brake on, giving the appearance that the plastic guards (whatever they are called) are slowing the engines down.  The engines then usually pick up power and continue, sometimes.

From your opening post regarding speed through the crossing, it sounds to me like Poliss has hit the problem on the head with his diagnosis.
Have you got pickups on all wheels?

Thanks for all the input.  I checked and double checked the voltage and polarity and all was ok except for one very small section and that was on the crossover exit.  The cause must be conductivity so I cleaned each side of the moving rail thoroughly with a very fine sandpaper then applied De-Ox to both sides. I also applied De-ox to the receiving fixed rail.  And whoopee I can now pass a loco through the crossover on setting Number 2 on the NCE controller.  I now know what to do if it starts to happen again.

I don't care what anyone says, you should never use sandpaper on the rails. Use a track rubber instead.

I appreciate that sandpaper is not recommended, however, I could not get the track rubber down the sides of the rail so I used, as I said, a very fine one.

But please make sure it is your own kid, please don't go hanging around outside school gates randomly trying to nick rubbers from kids or offering smarties in exchange, oh no sir, that could lead to all sorts of bother  :o

My success in getting the crossover to work properly was short lived.  I have decided now to remove it from the layout.  I appreciate that I could have had a 'dodgy one' and if I bought a replacement it would work without any problems, however, they all cost money.  To find an alternative way to do what the crossover did would mean a certain amount of track alterations which is not possible.
