Again, I have had no issues with K-Line Cruise working in TMCC, but it does seem they don't move normally in conventional. Units I have seen did not have an off switch. Nor is it discussed in the K-Line literature.
I have seen various instructions.
The codes are based on Lionel's stuff which discussed. I Have tried 4, 74, 34, 43, all which are codes various Lionel steam products used over the years.
These are R2lC with RS 4 via wire tether.
Just weird, and as Fred has stated some models do have different codes for the same basic steam engine.
Works great in tmcc so I don't worry. Customer wanted to use it conventional only, so I installed a DCDR and it worked fine. G
