The TMCC Direct Lockon has a problem with anything that generates electrical noise on the tracks, so many Pulmore motored locomotives will have an issue. FWIW, when I had these years ago, even a number of can motored locomotives would trip the lockon when I went past the track connection. Finally, add to that that the TMCC Direct Lockon kills the DCS signal, and that was the last straw. They were banished from my RR.
