A few weeks ago I got three Lionel TMCC lockons for my layout and I just got around to wiring them in. I run modern locomotives with a postwar 275 watt ZW and a KW transformer. So I wanted the lockons to protect the new trains. So now the new trains are safe, but my MPC Lionel 3100 trips the breaker after it runs for a little bit, I ran my Marx commodore Vanderbilt and had no problems, and my dc motor locomotives run flawlessly, so I’m thinking it’s just the Big AC locomotives, I haven’t ran my postwar 671 or 224 but I think they will trip the breaker, I also can’t run the conventional engines slowly because the track power turns on at a higher voltage. I drew a diagram for a switch that when thrown, overrides the TMCC lockon, the relay in the diagram is for when “AC motor mode” is turned on, it’s cuts power going back to the lockon to not fry it. I’m only 16 so it’s not perfect. I just want to know if it’s practical cause my dad says it’s to confusing, Thanks.525294DD-BBCB-4CB8-AB5C-418DED89CDBE
