Running Problems Track Cross Overs
Stuart model in OO and asks readers:
“Hi, has anyone experienced problems with Track Cross Overs (diamond crossings)and short circuit issues?
I operate my layout using DCC Control which works well except that two new locomotives that I’ve recently purchased (Hornby class 90 and a class 92) when crossing the crossovers create a short circuit, none of my other locomotive experience this issue. I’m at a bit of a loss to be honest so any ideas and hints would be welcome. Thanks in advance Stuart”
SUBMIT YOUR QUESTION
Check your back to back wheel spacing and also the tyre width. Depending on which brand of diamond crossing you are using, shorting ususally occurs when a wheel tyre or flange makes contact with the wrong rail near the frog.
Here is a connection diagram for a Peco O turnout, which is probably similar, and may help you to see how the connections go and the possible places a short circuit could occur. Look at the closeness of the opposite polarity rails as the loco wheels approach the frog, this could cause a short.
