Stephen in Kerry Posted December 16, 2021 Share Posted December 16, 2021 My 2 month old Hornby R3847 'Bembridge' Terrier was running fine today, and I was using it to rest track on my DCC layout following cleaning since ballasting.I took it off the track, to try other locos, and when I put it back, it won't move and makes a whining/humming noise when the power is increased (the noise doesn't happen when the controller is at '0').I've put a short video at this link, if anyone would care to take a look and offer thoughts on what might be happening, and how to fix it.https://tinyurl.com/ebuvv5jbThanks in advance.

Going Spare Posted December 16, 2021 Share Posted December 16, 2021 Has a stray piece of ballast got in to the mechanism? May have caused a gear to be displaced or broken. Link to comment Share on other sites More sharing options...
Stephen in Kerry Posted December 16, 2021 Author Share Posted December 16, 2021 Thanks @Going Spare. I took the body off, and brushed the gear. Didn't see any ballast, but when I put it back together it was running perfectly! Link to comment Share on other sites More sharing options...
Going Spare Posted December 16, 2021 Share Posted December 16, 2021 Good to hear your intervention worked, even though we don't quite know how or why, as can often be the case! Link to comment Share on other sites More sharing options...
96RAF Posted December 16, 2021 Share Posted December 16, 2021 Likely the motion rods were jammed and taking the body off then on realigned them. Something to watch out for in future. Valve gear and motion being so detailed these days is also incredibly fragile and shouldn’t even be handled when picking up a loco. Link to comment Share on other sites More sharing options...
