Hi guys,
I recognize those terminals! [Linked Image]

Those terminal blocks are railroad equipment. How many of them do you want. I have lots of them. Normally they come with Railroad lightning arrestors or other equipment. The hardware is 1/4-24. Normally 1/4 inch TPI is 20 or 28.

They are readily available, from Saftran, p/n 023612-1X.

Any of the big cabinets next to any crossing will be full of these things. Usually they are mounted under a part that would need to be replaced on a frequent basis, such as a lightning arrestors, or resistors. When you work with those really big parallel ground rods, you need to take lightning into consideration on any installation.

Looking at the picture again, it looks like the wire going to the barn might be railroad signal cabinet wire. Good stuff, most of it is rated at 1000v.
