I just received via Fed-X a Lionel 18" Aluminum Stations Sounds Car (6-25419). There were two loose tables rattling around inside. I was able to get them out with removal of the car ends. I thought I would glue the tables back in place, however, I can't figure out how to remove the shell. The shell will slide each way about an inch until the trucks hit on the side skirts. Do I need to remove the trucks? If so how? It looks like there is an e-clip holding trucks on but not an easy way to get at. I was trying not to remove trucks since it's a sound car with extra wires.
