Re: PSX-AR Installation Query


Hi Gang:

I think the suggestion is to have a short section of insulated and unpowered track, say 5cm. That way the two wheel of one truck can't connect the powered sections.

To avoid the metal wheel problem, simply glue a piece of styrene into
the gap and when dry sand or file to match the rail. The wheels will no
longer contact both rails at the same time.

Pete.  Your metal wheels explanation makes absolute sense. Thanks

As it was explained to me...
If you are running metal wheels, every pair of  wheels that crosses
the polarity gap will cause the Auto Reverser to switch the polarity
if there is a difference, so if your loco hits a second gap before the
whole train is through that section, the loco will switch the polarity
again and then  the wheels of the cars behind that cross the first gap
will switch the polarity again before the whole train is through
Your AR will be flipping back and forth as each set of wheels hit the
two gaps.
I hope I interpreted this correctly as I am new to DCC wiring too, but
I'm following the advice that was given to me as it makes sense.
