I'm still leaning toward the springs but wondering if MTH replacements might be weak to work with the automatic raising and lowering.
What about the height of the catenary ? Did you check it for being too low ? Years ago I tried operating my Lionel GG1 and my Lionel rectifier under the same catenary. I had built the catenary system for the GG1 but the height of the pantograph on the rectifier made it impossible to run the rectifier do to the pantograph not being able to stay up on it's own. The contact wire was too low and the rectifier's pantograph spring just kept releasing. I couldn't find a happy medium to run them both. The GG1 won out of course.
