Chrisjh Posted December 24, 2023 Share Posted December 24, 2023 I recently purchased a rake of the superb weathered BOC Tanks from Olivias Trains, but I have a couple of wagons which continuosly derail, just wondering if there is a fix? My other wagons run perfectly fine including my 100 TEA Tanks. Best Wishes and Many thanks Chris Link to comment Share on other sites More sharing options...

APOLLO Posted December 25, 2023 Share Posted December 25, 2023 I bought a few back when Hattons were flogging them off cheap and mine also continuously derailed. It seems a slight track twist / curve etc caused my problems. I eventually sorted it by changing the couplings with plug in magnetic ones. Forgot the make, they just plugged straight in. I left the rake outer couplings tension lock. Brit15 Link to comment Share on other sites More sharing options...
Chrisjh Posted December 25, 2023 Author Share Posted December 25, 2023 Many thanks the rake seems to run over the points and diamond crossings with no issues at all, so I hadnt checked the back to back as its only when it passes through over one of the large radii curves. It never seems to be the same curve either, but always the same wagon. I have even switched to magnetic couplings with no difference. Best wishes and thanks, Chris 1 Link to comment Share on other sites More sharing options...
Wolf27 Posted December 25, 2023 Share Posted December 25, 2023 Snip the small spigots off, either side of the bogie mounting. You need to removed the bogie first then you will see what I mean. 1 Link to comment Share on other sites More sharing options...
Chrisjh Posted December 25, 2023 Author Share Posted December 25, 2023 Many thanks that sounds like a good idea Link to comment Share on other sites More sharing options...
SRman Posted December 26, 2023 Share Posted December 26, 2023 I can't speak specifically for the Heljan wagons, but in more general terms with similar problems I have had with other manufacturers' wagons, I have found that once the wheel back to backs have been set, if they still derail or have problems, I look at the amount of movement available in the bogies. Often, if they are held in with a screw, a quarter turn looser seems to fix most of the remaining problems. If the bogies are clipped in rather than screwed, removing the bogies and filing a small amount off the face of the boss to allow more rocking fore and aft seems to be the main adjustment needed; occasionally they need a little side to side rocking allowed, but it is important to only do that on one bogie, otherwise you can introduce an undesirable wobble in the wagon's running. 2 1 Link to comment Share on other sites More sharing options...
APOLLO Posted December 26, 2023 Share Posted December 26, 2023 I have fixed some problems on my O gauge bogie freight cars by having one bogie "tight" (swivels OK but little / no roll) and one loose to allow easy swivel and roll. Done by tightening one and slackening the other bogie mount. Not 100% successful but helps a lot. Brit15 1 Link to comment Share on other sites More sharing options...
Chrisjh Posted December 26, 2023 Author Share Posted December 26, 2023 Thanks Gents I will adjust one of the bogies as suggested, many thanks Chris 1 Link to comment Share on other sites More sharing options...
Chrisjh Posted December 30, 2023 Author Share Posted December 30, 2023 Many thanks Gents delighted to say that the Porterhouse Magentic couplings have solved this problem for me, brilliant thank you.
