GREGR, I did not think to go to the Train Tender because I never heard of it. I am throwing away all the Lionel silver 3/16" E-clips because they are opening up on my 21" passenger car truck posts. I had three cars arrive with the trucks dangling by the wires. About another dozen clips could be flicked away with my finger, no tool required, just move it away easily.
The silver e-clips were opening under the movement of the truck post and the floor of the car, bending open the e-clip. Going to a Lionel train store was the last thought on my mind. I appreciate the info. I just wanted explain my thinking: "Train part fails. Don't go to train store for parts."
Sincerely, John Rowlen
