I have a few Lionel trains, I'd like to run with one control system. Two Lionel trains I'd like to run linked on the same track, one is a Norfolk Southern TMCC P/N 6-28204, the other a CSX Legacy 6-38407. Also my B&O 6-28615, on a separate track I'd like to upgrade to DCC, so that I can make it possible. What are my options, do I need a Lionel Legacy system? Or are their other manufacturers that their systems will play nicely with my trains. Additionally what other electronics would I need? Does it matter that the B&O is not TMCC, or legacy? Is there a way, to put in a board, and upgrade it? I've been running conventional setups, now I want to start getting a bit more serious, and would appreciate the advice!
