For whatever the reason, my FEF3s are going through traction tires like crazy. Two questions for you guys. 1. Do you thing the abrupt side thrust of running all Unitrack rail could cause then traction tires to try and slip on the drivers? All of my curves are super elevated curves. 2. Does anyone else use adhesive to try and keep the traction tires in place? For a while I used Bull Frog Snot as an adhesive to hold the traction tires in place. Now I am using a clear Elmers Glue product. So far I have about 6 to 7 hours on the Elmers.
