Yes but the hole idea is to run both. If I have to eliminate one brand it will not be Lionel.
First find out if there is an interference issue with any of the MCC/Legacy engines. Then, once you know which engines. if any, are part of the problem, there's a very simple correction that you can make to them.
After you remove your TMCC and you find out that you probably have an interfearence
problem, you might try adding some Lights along your track to help with your signal loss
If the engines are the problem, you can't correct the problem through additional blocks or light bulbs or filters. The engines themselves need a slight modification by inserting a RF choke between the pickup rollers and the TMCC/Legacy electronics.

OK I see now. I do have your manual and have found it very helpful. I should probably re-read it.
