Have re-read this post but its late and I haven't had enough wine today however. Are the points fitted with insulated rail joiners at the frog or "exit ends" . Power should just be coming from the single track end or you will get a short circuit. Time for bed now...zzzzzzzzzz

Quote from: bluedepot on July 22, 2012, 11:34:14 AMthis problem is common to all my dmus.

I've got a 108... does this mean I will have to cut the rails between the frog and point blades, and connect them to the outside rails like is done on OO gauge?  I thought this wasn't neccesary in N?

It isn't necessary in N.

i'm going to try and get a wider back to back gauge (7.54mm) and see if some wheel adjustments help....

it is very frustrating to hear that other people have no problems!!! yet i use large radius electrofrogs and have all this!!!

yes i do have insulated rail joiners in right places.


cheers

Have you tried the stock on other people's layouts ?

I did suggest that sometime back in the thread but he hasn't confirmed.

Also is it all the points (on the layout) or just a few. If there are some that are never an issue it would seem the train is mostly okay.

Is it only on particular point route settings?

Does it always short when running over the points?

Try and narrow down the circumstance it occurs.

hi,

sorry, nope i've not tried them on other people's layouts.

it is worse on particular route settings, but there is a random element about it as well. sometimes it passses ok, other times it shorts out!

i will try some wheel widening to 7.54mm and see what effect that has. the gauge i was using was a nairnshire modelling one, and i read that this was actually 7.4mm... so a bit too narrow perhaps.

i'm in a better more positive mood today, because the sun is out!!! hahaha my n gauge is safe from ebay for now!!! hahaha

cheers


tim

hope it works!

not run on all routes yet but after wheel adjustments to the 108 and 150 they haven't short circuited yet....  and i ran them round the short loop routes about 15 times each (and a few times in the other direction on the wrong line)

first i did some over adustments and ended up with broad gauge... so then had to narrow them again...

anyway, here is a poor quality video!

cheers

looks good

Looking good, at last count I have four 101's and a new 108 (don't know why I collected so many!!), none of them short over any points so I would check how you have secured the points to the base board, my points are "floating" which probably saves distortion..

In fact the only loco I have trouble with is a class 31 which wobbles about like it's drunk, however I suspect this has a bent axle somewhere

  Nice to see so many of us are in a rage, keep up the great work lads the Cardiologists and shrinks are making a fortune

That point 'wobble' is usually because a wheel drops in to the crossing gap (Peco points have huge flangeways) due to the BtB not being set correctly.

Not point wobble H, wobble anywhere on the track

That point 'wobble' is usually because a wheel drops in to the crossing gap (Peco points have huge flangeways) due to the BtB not being set correctly, but easy enough to sort out even if you have to replace the wheelset.

Then I doubt it's bent axle - more likely a non concentric wheel (damaged/lost tyre or collapsed bush) or a wheel is no longer square on the axle.
