You're right, getting them back was trickier - the technique I adopted was to pull them through with pliers at 90deg to the plane of the points, not to push.
,
When people eulogise about the quality of Kato I am not fully on board - surely the points should be made this way to start off with!!
Thanks Jon, good one, I had not thought it thro' in that direction ! :)
,
I totally agree, the prob has been known about for years ! so if they can update the ballast mouldings ( flat printed ? to embossed textured ? ) then why not address the notch prob., velly velly odd !

I wonder if it's something to do with the fact that Kato trains seem to cope with Kato points just fine. At least in my hitherto unscientific observations.

Hi there!

Apologies if this is covered elsewhere, and I've missed itů

I have a Kato scissors crossing which appears to  be dead in the middle, in the diamond part if you follow me. Is it meant to be like this?

 :confused2:

I've taken the back cover off, nothing appears to be amiss, but I can only runs train through it at fairly high speed (the momentum of the train carrying it across). Any help/hints/tips gratefully received!

Hi David

My Double Crossover ref 20-210, is isolated across the middle, which means I need power supplied to both ends of both tracks of the unit. Other crossing may well be configured in the same way.

Does this help in any way?

Ray,

Thanks, can you run a loco (Bo-Bo diesel or tender engine) across it slowly? I use two controllers too, but nothing I have will go across it slowly, in fact they have to charge across at about a scale 50 - 60mph!

I was wondering if there is supposed to be a big gap across the crossing to stop short-circuits, does this sound like yours?

I don't recall any problems but will do a couple of tests later today and let you know.

I have just got the same problem but mine was working perfect until last week I think it is down to a contact within the points as when I put a little pressure on to the point where it is dead then it comes live again, I have the sissors powered at the 4 ends so why I am getting this problem I do not know.

More of investigation needed.

Geoff,

Thanks that's very interesting, it sounds like there is a contact in there that isn't very obvious. If you find anything please let me/us know!

Regards,
David

Just run an old Farish class 47 through and accross my double crossover at crawling pace with no problem. A modern Class 08 (Ivor) needed at bit more power so went a it faster but still no problem. 

So the idea of a contact needing tweaking sounds resonable (to me at least).

David sorry for being a long time with the answer, I have had the back off and I found the problem after a bit of investigation and I feel it is down to poor design of the crossover that is causing the problem, 1st there is a flimsy copper T section held down by a small screw take this off and bend the contacts down then replace, also there are contacts that come up from the rails and are ony bent over onto a copper contact board and this needs to be gently pushed down, I would of used contact grease but there are lots of fine bare coil wires which I did not want to make contact with, but I do feel this could get dirty again hence not a good design on Kato's part maybe they should of been soldered.

Anyway my crossover is fully working again, just be careful when removing the back as there is a tiny plate that holds in 2 small springs which tend to come out when fiddling with the crossover, they are fiddly to re attach but easy enough.

Re those small wire springs on the crossover. I found that if you accidentally operate the crossover while a loco is on top of the wiper blade, it can cause those wire springs to disengage from the small rings on the switch blade. As Geoff says, fiddly to reattach, but doable. They should have been made a bit longer with possibly a short L section on the end to stop them pulling out.
I'm not sure if life is passing me by, or trying to run me over.

Thought I would add some photos of inside the Crossover.



In the above photo you can see 4 sections that come through from the point rails and bent over with 4 dimples, the dimples are meant to give a good contact onto the powered copper section and this is what was causing the problem and with a gentle push down it seemed to sort out the problem, no doubt this will happen again, also the t section had to be removed and bent down slightly to give a better contact when switching.

I don't know if this has been covered before, but...

some Kato points have a plug in lead for point motor control (it's hardwired in the no6 but a separate plug-in connector item in the no4 and the unitram points, and others)

I'm concerned that if I fix down one of these points in a permanent layout, that the lead might get an accidental tug one time and disconnect, and due to its location it would be hard or impossible to reconnect it without ripping the whole thing out.

Anyone got any tips or suggestions on making sure this lead remains attached?
