Why are tension couplings still legal?

No other forms of torture are still allowed. Has anyone actually checked the Geneva Conventions? 

Just buy yourself a pair of Xuron track cutters, chop them off and fit something decent (which means pretty much anything else).

At least the modern tension lock couplings are not as bad as the giant ones which Triang used to use in the 50s/60s. 

 

Coaches a scale 10ft apart just to go around 24" radius curves?

 

Those were the days.

Could be worse - have you tried to couple 3-link or screw link under a corridor connection whilst the public watch you at an exhibition.......................?

The Hornby Roco style close couplings when fitted to Bachmann Mk1s are bad enough thanks Mick....

More like a scale 6ft, IIRC.

 

The loops of the big Tri-ang couplings were much wider (as were Lima) but they hardly stuck out any further than today's so-called mini ones.

 

Any reduction in slack is down to the hooks being shorter now.

If you remember, we all quite liked them as children, which is who they were for in the days before, to quote that bloke off the telly, model trains became the preserve of ‘sad middle aged men’. And, I smile when I read articles in RM that say things like ‘now I’ve got older, I’ve given up on three-link, and gone back to tension lock’.

 

So, they have their place.

Modern tension locks would be ok if only people (at exhibitions) used them as intended, that is, automatically.

Why people keep these couplings and then use a shunters pole/bit of wire to operate them beats me everytime!

I've used many forms of couplings over the years, but IMO the tension lock requires the least adjustment, maintenance and care.

 

Other forms of coupling require regular checking and resetting as required.

 

Yes - it isn't the prettiest, but is usually the most reliable.

I didn't like them, I liked Hornby Dublo ones and I still do!

The market for toy trains has been used to these since long before Hornby became the brand name for what had formerly been called Tri-ang. It would have been economic suicide for any radical change of coupling to be foist upon that market. The smaller version now usually found on rtr rolling stock suits the traditionalists - and as pointed out, yields readily to removal and replacement by other varieties of coupling, especially those with NEM fittings.

I wrote to Pec last year to ask them if they made or considered making their version (simplex?) with a plug in NEM fitting. They said no they didn't but would think about it. I am sure they would be very popular as I think they are much more convenient than any other couplings on the market.

Hmmm they DID consider it; in fact such a system was described in the Modeller in some detail a couple of years ago, but they have told me that they were unable to make it work satisfactorily and didn't proceed with it.

I am afraid that I doubt if this could be done.  The HD (Peco Simplex) coupling relies on having the big pivot somewhere behind the buffer beam (to get the correct spacing between vehicles) and the coupling is on about the same level as the pocket. The only way I can fit HD couplings to modern wagons involves destroying the NEM pockets.

Sixty odd years ago when making the first steps from Train Set to "scale" modelling fitting scale wheels and three link couplings was standard. Now at the other end of the age spectrum I find the need to go back to autocouplers!

I think that was the nub of their problem.  The Peco person who told me they couldn't make it work said that during testing the last vehicle kept becoming detached.  From my experience of using the metal Peco (or HD) Simplex couplings, this could happen if a vehicle had couplings that weren't entirely free to pivot from side to side.  The last vehicle doesn't have the weight of the rest of the train behind it to force the coupling to swing on curves, especially with modern free running rolling stock.  I suspect they were trying to use a thin plastic 'pivot' (like the flexible piece in the Bachmann / Hornby "NEM" tension lock pockets), which probably would act as a centring spring rather than being flexible enough to let the Simplex coupling swing freely.
