COUPLINGS FOR LGB LOCOS ETC

by Julius de Waal


THIS article contains five different types of couplings to LGB scale (1:22.5 - track 45mm) and this article is directed to the people who already are owners of LGB trains and who would like to explore the possibility to change their LGB coupling to a more prototypically type of coupling. I am the proud owner of a number of LGB locomotives and rolling stock.

When one buys a standard LGB goods wagon you notice that the wheel axles can swivel around the vertical axis and that the pull hook is a part of the swivel mechanism.

Personally, I do not like the way the wheel axles on a 2-axle (4-wheels) goods wagon swivel vertical axis, and also do not like that the coupling hook is attached to this swivel mechanism. In reality the wheel axles are fixed in place. The reason why LGB designed this swivel mechanism was mainly to get the wagon smoothly through the small radius bends and the small radius points/turnouts.

Since I found the LGB coupling big, ugly and cumbersome to uncouple I was looking for some alternative type of coupling which I could place on my rolling stock.

I had a very large shunting layout and to make it easy for me and my friends to uncouple the wagons I looked for another type of coupling.

As one looks at photographs of the real engines and wagons, one can see that couplings are different from the LGB ones.

LGB also make an “American knuckle coupler” (LGB code 2019/2) which is aimed to the American railroader.

Now let’s take a look at the drawings. (CLICK ON DRAWINGS TO DOWNLOAD TO FULL SIZE)


DRAWING: CPLNG-A

This drawing is based on couplings used by the New Zealand Railways. To make this type of coupling is a bit of a challenge, because of the complex curve arrangement. However, if you manage to make one then it is easy make a mould of it and cast as many as required.

The coupling attachment (part 03) is the same as the LGB type. This could be a direct replacement for the standard LGB coupling. In this case the axle swivel mechanism can not be fixed.


DRAWING: CPLNG-B

This drawing is based on couplings used by some railways in different countries. This type can be bought of the shelf because it is produced by LGB.

This type of coupling was given to me, a long time ago, by a friend of mine who bought it in England as a sample. It does not have an LGB attachment, just a flat back plate which suppose to be screwed to the buffer beam of the wagons.

The original sample could swivel. However, on my drawing I have shown the coupling attachment (part 03) is the same as the LGB type.

This could be a direct replacement for the standard LGB coupling.

In this case the axle swivel mechanism can not be fixed.



DRAWING: CPL-D-C

This drawing is based on my own design, called pin and hole coupling. To make this type is easy simple and cheap.

I made two types; one was made of 6mm square aluminium bar and the other out of a 152mm (6 inch) nail.

It can be seen from the drawings that I glued a fibre washer at the end of the aluminium bar and then drilled a hole in the end. For the pin I used old 4mm round nail cut it to length and press fit it into the aluminium bar.

Most of my wagons had this type of coupling because it was easy to remove or drop the coupling pin (part 03) into the coupling hole. The swivel mechanism of the wheel axle could be fixed because the coupling can swivel.

Since this type has no LGB connector, one has to make a little modification to the wagon to attach this type of coupling. A simple modification is to drill a 2mm in the existing coupling connector and attach the new coupling using a small self-tapping screw.


DRAWING: CPLNG-E

This drawing is basically as per drawing CPLNG-A. However, instead of having the complex arrangement, a pin is used the hold the hook in place.

The coupling attachment (part 03) is the same as the LGB type.

This could be a direct replacement for the standard LGB coupling. In this case the axle swivel mechanism can not be fixed.


DRAWING: CPLNG-F

This drawing is based on a coupling which was given to me.

This type of coupling is readily available in the USA and a lot of American railroaders use this on their timber or logging wagons and also on their bush tram railroads.

It does not have any LGB connection.

The sample I have is cast white metal alloy. It has a flat back plate with a protrusion so it can be mounted straight onto the buffer beam.

This type of coupling can only be used on bogie type wagons or logging trucks.


I hope the drawings are clear and I hope that this may inspire you to experiment to design or make your own type of couplings.


Happy Modelling!
