I have picked up their parts at East Coast. Warrior Run has their product line with nice pics -

Been using their stuff for years. Top drawer in terms of quality. I haven’t ordered direct from them since the business was sold a few years ago, but the local hobby shop seems to be able to keep ample supply on the shelves.

I’ve gotten some stacks from them via TOC. Really good stuff!
Happy RRing,

Also been using them for years, going back to my HOn30 days, stuff was a hellova lot cheaper in HO though 
Like Kevin says, top drawer stuff, top drawer prices as well, I have found it best to use a mix of white metal Ozark parts in the places less vunerable to impact or bending and using brass Trackside parts where wear, impact, and bending are more likely.
Like Kevin and Vic have said, top drawer stuff. The castings are almost like “lost wax”. Outstanding quality and definition. Prices are not too bad considering I have bought marker light castings for my 1 1/2 caboose and those were $75. But the quality of Trackside Details and these were comparable. The photos on Trackside Details website, of their products, don’t do them justice!
I was a customer of Trackside details for many years while Pete was alive. A gentleman and a nice person.
After the business was sold to Valley Brass and Bronze it came to another vendor of mine. David Sciacca has been doing many castings for me over the years. Excellent work and another gentleman in the business.
Gary, These are lost wax castings. David has been casting the wheel centers for my C-16 wheels and Baldwin 2" wheels for many years, no complaints (except the price of brass has gone up, David can’t fix that).
