tired of your front trucks derailing? today during weekly sessions at my model train club i noticed the front truck kept jumping the rails. to solve this problem i put a small spring in the front under the truck. it will only require a small piece but will hold the truck to the rails with a good strong grip. hope this helps others with similar problems.
Sounds great. Would enjoy a diagram or something, if possible.
basicly all i did was removed the bottom part holding the wheels in and put the spring on the small rod that the front truck goes on then i would test the engine to see if the drivers where sitting on the rails if they were not i would cut the spring smaller and try againg until the drivers sat securely on the rails.
this should help...(http://i1256.photobucket.com/albums/ii494/chesapeakeandohio/untitled.png)
