Pic #5 looks like an old school(?) transistor if those are 3 legs in each. If there's any with 4 legs, those are usually bridge recitifiers.

So as I said above, if it looks like a rail joiner, it is a rail joiner, even if someone wants to call it a fishplate.

The SW-51 (61?) extra contacts are for the switch machines that NJI used to sell.  I think I said that above, also.

The SM-106 Scale-Like Industries things are slow motion turnout motors.  They are in all probability re-purposed Hankscraft display motors.  Similar items were sold by an outfit called Electro-plumbing and I think one or two others.

Oh, I agree completely. A rail joiner is a completely different kettle of fish...

#1 are optical detectors.  They know when a train is over them because it blocks the ambient light.  Used in crossing or block detection generally.

#3 are replacement relay points.  For what particular relay, I can only guess.

#5 are transistors.  If you have access to a transistor testor, you can figure out if they are pnp or npn.  All kinds of applications for those.  I love old transistors like these because each of those is one transistor, but your smart phone has trillions of the same thing in it.

Larry,

That's a good example of regional or even RR-specific variation in terminology.

The package of "fishplates" says "used in Kit No. 709"  I checked the Mantua catalogs on the HOseeker site.  Did not find Kit No. 709.  In the 1955, 1959 and 1960 catalogs kits 701 through 706 are truss bridges.

--------

No. 707 and 708 are "Circuit Breaker Kits"  Found 709 on a list "Fishplates, envelope 100"  - No help!

 --------

There are several lists of 4 digit part numbers.   While "5616" does not appear on any of them.  It is obviously  a renumbering of "709"

I tried to sell my two cents worth, but no one would give me a plug nickel for it.

I don't have a leg to stand on.

For the third time, I believe that they are extra contacts for the switch machines that NJI used to sell.  You can see some installed on the machines at the following link: https://www.google.com/search?q=nj+international+switch+machine&rlz=1T4GGHP_enUS443US443&tbm=isch&tbo=u&source=univ&sa=X&ei=_0UaVPGWFYqhyAS2x4D4CQ&ved=0CB8QsAQ&biw=1024&bih=579
