rob_brewer Posted April 7, 2015 Author Share Posted April 7, 2015 Good MorningThank you for all the replies I do appreciate your comments and thoughts.Fishmanoz your response is exactly what happened in my case.The heating only occurred at the clip on the track to which the point wasn't set and only the one clip was hot.Yelrow Two of my points started to melt at crossing points but the one which heated up quickly and melted at least an inch by the frog was a lone one not far from the above.Rob Brewer Link to comment Share on other sites More sharing options...

Do you use a DCC bus with droppers, or do you have a single point of connection?Ray Link to comment Share on other sites More sharing options...

St1ngr4y Posted April 7, 2015 Share Posted April 7, 2015 Good Evening RayI have a single point of connectionRobIn that case I'll repeat a point I was trying to make in John's Melting Points thread...I believe if the power from your point of connection can only pass through a particular point clip to reach the parts of the layout where, for example, your locos reside, then bad contact here will lead to the overheating. Having a bus with lots of droppers will prevent these hotspots.Ray Link to comment Share on other sites More sharing options...

PJ_model_trains Posted April 8, 2015 Share Posted April 8, 2015 Well done Ray, At last we have a good example, proving the point being stated over many months, a DCC Bus, as recommended by the specialists is very important. The DCC Bus, provides a uniformly distributed load, (power to every dropper). A single power point creates a point load of which ALL power must pass. As you have stated above Ray, if these clips create a bad connection, although they may seem to be seated correctly, power struggles to pass which then causes over heating. With a single power source, any bad or poor connection can cause over heating not just the point clips, the point clips are more likely to causd an overheating issue than a fish plate, damage is also more likely (to be seen) on a point than on a joint between two sections of track. The specialists state a DCC Bus should be installed. Link to comment Share on other sites More sharing options...
