Holloway Goods - Using Mr Peco's Nuts

Hi All

 

It's been a long time since I've had the time and inclination to work on my model railway. However I recently been working on coupling design for Holloway Goods.

Mr Peco's nuts are used to hold the wagon body to the chassis, with the weight, held in position, between them. This method is better then glueing because it allows the components to easily be disassembled if required!

 

My design criteria are that the train should be able to negotiate a 75mm radius curve reliably without derailing. The actual minimum radius will be 90mm, but if the above condition is meet, then I shall have no problems on the actual layout.

The picture above, was taken on a friends micro layout, which has 75mm curves to minimise the area taken by the fiddleyard.

 

I have no objection to the coupling system being single ended, that is to say different couplings on each end of vehicles. In this project I kept the peco coupling on one end, but I have filled the thickness down to half the original. I tested a coupling to see if it remained coupled and it passed the test. The thinner coupling is less obtrusive, then the original.

The other coupling is replaced with a simple hook, made from stainless steel G String, purchased from the local music shop.

The front angle of the hook is about 60 degrees, it is important that there is sufficient gap to allow the modified Peco hook to drop under it's own weight, even when a magnetic dropper is added.

I wanted the train, composed of loose coupled wagons, to close up when the train comes to a stop, say at a signal, and open up as the train started again.

Hi Julie/Lisa (?),  I think we all have these times when inclination is lacking  In the recent hot weather my work-room has been too hot to contemplate any activity!

 

I notice that on your tight-curve photo, the buffers on one of the wagons looks to have been removed.  I would have thought that buffer-locking is the main problem on such tight curves, whatever type of coupling you use.

 

Also beware of nuts coming loose!  A little threadlock adhesive is advisable, since they always seem to fall off in tunnels :)

Hi

 

I'm posting using julie's id, because i've had problems with my email address, thus I currently can't access my RmWeb id either.

 

The missing buffer was the result of an accident with a scaple.
