The LCN&J RR just purchased a new Lionel BN SD-70 ACe from Lionel and it arrived today. The # is 1970 ( my birth year). We run our engines conventionaly so I would recomend a 9v alk battery before operation. It seems the horn would not work under 11 volts and it would just shut the engine down. After placing a battery in the engine it ran flawless. We use a MTH z-4000 with Fastrack, the curves are o-36 to o-60. This is our 1st higher end Lionel so I am still getting use to it. I did not have the smoke on sorry about that. The engine arrived in excellant condition, very shiny. Make sure your hands have no oil or lotion on them, the black shows fingerprints. Here is a short video of it starting up, in operation and shutting down. Some photos too. Nick
