Try Scalelink Ltd.3 link couplings are fine so long as you are hauling. If
you need to propel the wagons,i,e, shunting, then you could have trouble
with buffer locking on sharper curves. One way round this is to either 1.
Glue a strand of fine wire between to buffers, or 2. Glue on some larger

Or fit sprung buffers, just like the prototype!
You might find the thread on adding magnet remote operation to tension locks
Otherwise, yes you can fit proper scale chains. Some are easier to couple
than others, and there are some who prefer a steel end-loop (non-ferrous for
intermediates), so a magnetic hook can be used to aid the chain onto the
adjacent wagon. I find Exactoscale ones work well, but they are expensive,
many other makers are cheaper. As others have said, buffer locking when
propelling round tight curves or tight turnouts might be an issue.
Having mentioned Exactoscale, its worth reading their documentation,
particularly on how to open/close links in chains.

I used scale couplings for many years in 4mm scale without any problem with
buffer-locking. The key is to have scale sized buffer-heads and avoid
curves of less than 2'0" radius. Cross-overs can be an issue, but providing
their radius is sensible, it can be avoided.

Well of course, but then that is half the 'art' of scale

The main problem with crossovers is the S-bend in the middle. What you
really want is a straight section, as long as possible. So the best
thing may be to build your own, or in OO use a pair of Peco code 83 No.
