My new 4-6-0 front truck has had a problem of derailing. After relaying track to be sure all was snug I finally looked at the front truck and saw that there was No spring or tenson piece to help hold it down. I "think" I have solved the problem by wrapping a single strand of solder around the truck, Not an elegant solution but it can not be seen unless the engine is turned over.
Seems to me it should have a spring or tension to hold the wheels down on the track,
Anyone else have this problem and how did you solve it.
