Hi I have several Lionel TMCC engines without speed control, ie Norfolk and Western 1218, and the Union Pacific 4006 Big Boy, and several diesel engines. I am looking for the information to convert these to newer speed control, I'm ok with rail sounds 5,0 but need more control over the engines speed. A lot of what I am reading here is about other brands and some acronyms I don't know, thank you for your patience with me. Regards John
