I have had a train
load of trouble with Bachamnn wagons derailing going over Hornby points. It doesnt matter what loco pushes/pulls them bachmann orHornby as soon as they hit pointsoff they come. To be fair its when I use points to form a cross over from one circuit to another to form a sort of 'S' shape. Hornby wagons and Dapol ones go over no problem. I have eventually solved it by replacing the couplings with Hornby'D' shape ones. I also have a Bachmann loco its a class 56XX, beautifull mover (DCC) but oh dear anywhere near points as above and any wagons it has derail. So in the end I have replaced the coupling with a Hornby, result? perfect over any shape points even pulling 8 wagons at atime. Has anyone else had this problem?

Hi Zach,

I have been doing it the other way round and getting rid of my Hornby couplings and have been fitting my stock with the small Hornby plug in,Bachmann small screw on type. They are ok but have to make sure not to couple/uncouple on a curved piece of track although my indoor layout ( 8' x 2' ) doesn't have very sharp curves the hooks sometimes cross over and throw the wagon off.

I too find that coupling my Bachmann rolling stock extremely difficult to couple over curves (2nd and third ratio). At times Bachmann locomotives decouple on straight track (set track).

Funny you should say this, Zach, because only this weekend I have been spending precious time and thought on experimenting with this very issue. Sadly, I don't have any advice to impart, but I have certainly found reliable coupling problematic (oo-er missus)
.

Bachmann's coupler heights on wagons, especially, do seem very erratic. I know that's a factor, as they slip under or over whatever they're coupled to. Heljan's small tension lock (on their 47) is too loose and feeble to reliably propel Hornby Mk 3s. In fact the shank actually bent on mine. Hornby and Peco uncoupling ramps have different degrees of compatibility/effectiveness with different stock. And so it goes on.

The really wearisome part is the time and effort it's going to take to identify and fix each combination of problems. I have got hold of some Kadees and want to experiment with those, at some point.

Another idea I want to try is to use fixed rakes, e.g., joined by instanter or screw-couplings, topped and tailed with whatever turns out to be the best "operational" coupling method attached at each end.

As many wiser and older hands have observed, "Standards" seem to be a pretty hard thing to come by in UK 00/4mm scale these days. I'm beginning to understand why some people lament the old days and the Big Fat & Ugly ™ tension lock couplings.

Hi Zach and Paxman,

One thing I use to check this is a small wooden block 2 grooves the gauge of the track ( mine is 9mm thick ) and cut to the right depth gives a coupling height gauge. This will the identify the wrong height ones.

Back to sex in model rail?

But seriously I have an assortment of couplings on my varied British HO fleet, and have decided to go with the Fleischmann profi as a means of unifying. My reasons for this choice are two fold. 1) They actually couple and 2) they don't look too bad. Additionally I don't have couplings on the leading ends of most of my locos or trailing ends of the last coaches.

Regards

John

Using a height guage (small wooden block in my case ) if the coupling is high in the use of Bachmann 36-030 NEM pocket type, just ease it down in the locating groove or put a piece of packing under it If it is low the top of the fixing lug would need filing, bit of trial and error. Other couplings should not present a problem, I have used the above and 36-025 standard and 36-026 long screw on type and Hornby R8220 push in. I also have some stock with Dapol push in, for this and the hornby wedge a thin piece of plastic or card above or below as needed.
