The short answer is the inevitable track maintenance. .110 connectors are too loosey goosey for my taste. If you try the brass .080 you will see.
I crimp the feeder into the connector then flow solder into the connection. (These connectors do not have the plastic base). You just have to keep the solder away from the female spade end and just where the wire crimps. Goes on right, holds tight. NEVER had one loosen up since I changed.
Hi Volphin, on the above 28-6082, what is the maximum gauge wire that you can crimp into the connector?
Thanks!
I have only used 14, 16 and 18 Ga on this connector for feeders and buss applications. Seems to me it could go a little larger, but I haven't tried other gauges. It's not like you need battery cable for model trains anyway... 
My nominal buss size is 16 Ga w/ 18 Ga feeders on my 250 ft Fastrack layout. I do not use shrink tube on them... no need.
I use them for accessory power buss feeders as well, and those little wires are tiny! Right now they are soldered into my GGD coaling tower, Broadway Ltd. water tower, Lionel hobo water tower, Lionel hobo hotel, and a PE hero boy's house.
Hope this helps.
