I recently bought a broadway limited pacific 4-6-2 engine and many times when it goes over switches it stops, then a few seconds later will usually start up again. Sometimes you have to give a push before it starts going again. Someone wrote this was a know problem and there is a part you can install. What was the part number, does anyone know?
I once had that problem with a 4-4-0 and it turned out that a tender wheel set was out of gauge. Too narrow and caused a loss of contact when going slowly over an Atlas turnout. Just a thought.
There are several things that can cause this; a momentary short due to a wheelset bridging the gap at the open points (not usually on Atlas turnouts, though) or at the frog, or a momentary "open" circuit caused by poor electrical contact to the points or closure rails (pretty common on Atlas). This can sometimes be mitigated by applying a tiny drop of DeOxit or NeverStall on each of the rivets that are the pivot points for the points. In the case of DCC, if the problem is a momentary open, adding a "keep alive" capacitor circuit to the decoder will also help. Loss of contact can also be caused by an imperceptible twist in the switch that causes longer unsprung and unequalized locos (usually steam) to lose contact as they move over the turnout. Bill in FtL
Both the engine and tender should get current from the rails. Start up the sound, lift the tender off the rail and see if the sound stops. Then lift the engine and see if the sound stops. Make sure the plug between engine and tender is pushed in all the way. You might have to adjust the electrical contacts on the tender to put more pressure on the axels. Bob
