Two nights ago I lubricated one of my old British 00 (similar to HO) locos with Wahl oil and I was amazed at how smoothly & quietly it ran afterwards. (This is a Hornby Dublo loco made in the early '60s.) When I ran it again tonight, it continued to run well although I had to often wipe up some excess crud from the tracks -- which often happens after using Wahl oil. This is a side benefit because it causes me to clean the track (Wahl oil is supposed to be good for this).
Well, tonight I noticed a couple times that some fine smoke was coming from the loco and I could smell a faint burning smell!
I was running it off & on for about two hours and this happened mid-way through. After a few minutes, this smoke/burning stopped. The loco ran well the entire evening though, even when the smoking was happening.
I suspect that the motor was simply burning off some excess oil or debris but I just thought I'd ask folks here if there could be anything else causing this.
Thanks!
