Wheel back to back measurements

When I completed the track laying on my fiddle yard, I noticed that two of the five locos I was using for testing where shorting my ECoS when travelling over points. Great I thought a problem with the wiring. Thankfully, the wiring appears to be ok. That leaves me to suspect the back to back wheel measurements as being a problem as the other three locos have no problems.

I then bought the C&L back to back gauge for 00:



However, I am not sure how best to use this gauge. I believe the measurement between the wheel backs should be 14mm, is this correct?

Also, is there an easy way to adjust this on locos or does it involve a complete dismantle to prise the wheels further apart?

Sadly I suspect this will be a problem with quite a few of my locos and I guess is an unfortunate side effect of DCC as it comes with the required better sensitivity of boosters that forces you to use best operating practises!

Hi Richard,

I have the same question relating to N Gauge. I don't know if I have a problem yet but might as well get my locos checked out now. i.e. What is the best b 2 b and do you do the necessary kit?

Regards,

Expat.
