Occasional sound drops out on lionchief Hogwarts

Sounds like a wire is frayed in either the loco or tender.  Usually on the loco where it connects to the tender.  I've had similar issued with other Lionchief trains.

Thank you for your reply janitor John, assuming that is the issue, is there a way I can fix it? Thanks again

Find where the wire is broken and solder a new wire into place.

If it is a frayed wire, I found a product called liquid tape. It comes in a small jar and has a brush on the lid that makes it easier to apply to your frayed wire. It's meant to help cover up and protect frayed wires, basically like regular electric tape, but since it's such a small wire in a confined space, this would be the best option. It has to dry for 24 hours before you can use the item it's applied to again, and is not supposed to chip off, or crack. Would this be a good option to use if it is a frayed wire?

I took a closer look at the engines drawbar and noticed that on one of the 4 metal prongs, there was a small black speck of what I assume is some sort of build up, so I carefully scraped it off, and now the engine drawbar is clean as a whistle. So I put it on the track and ran it non stop for about 10 minutes straight, and so far haven't heard the first issue whatsoever. Perhaps that speck of buildup on the engine drawbar was the issue?

Usually Tuner cleaner works better to clean the pins..   But sounds like you found the problem.

Sounds like you got it!
