Arnie’s Model Trains tees up MAC Rail visit in Westminster, California

Greg McComas of MAC Rail is set to visit Arnie’s Model Trains in Westminster on Saturday, July 18, 2026, and that makes this more than a routine shop stop. For Southern California modelers, the draw is simple: a chance to catch a guest appearance inside a store that already functions as a serious railroading hub, not just a place to grab a boxcar or a length of flex track.

Arnie’s is at 6452 Industry Way #A, Westminster, CA 92683, and the store says it is open Monday through Saturday from 10:00 a.m. to 6:00 p.m., with Sunday closed. It also describes itself as Orange County and Los Angeles County’s largest model train store, with a focus on HO and N scale. That combination matters because a shop like this is where a quick errand can turn into a longer visit, especially when a guest from MAC Rail is on the calendar.

The store’s service side gives the visit more weight. Arnie’s says it offers DCC and sound upgrade and repair work, and its technicians work with SoundTraxx Econami, Tsunami2 and BluNami decoders. That is the kind of support that makes an in-person appearance useful for operators who are sorting out decoder installs, sound problems or upgrade choices before they commit to a project. A visit from MAC Rail adds another layer, because it gives regulars a reason to compare notes with someone who knows the products and the realities of keeping a layout running.

Arnie’s also has the kind of backstory that explains why it keeps showing up as a local destination. The business says Jerry Arnold and his son Greg Arnold, nicknamed Arnie, started it in 1975 on Westminster Boulevard in Westminster. Next door, Milepost 38 says it and Arnie’s together make up a Model Trains Super Center with more than 7,000 square feet of trains and accessories. That is a sizable footprint for a hobby that still depends on face-to-face advice and hands-on shopping.

The MAC Rail stop fits that pattern. A guest visit, a big store, repair skills and a broad HO and N scale inventory give modelers a practical reason to make the trip, not just window-shop online. In a hobby built on details, Arnie’s is using July 18 to remind people that the best ideas still often start at the counter.
