Graham has been shopping on eBay and picked up a few new models. This week, he shows off his new Atlas Master engines, which he upgraded with Blunami decoders. George also shares his GP15, which he upgraded with Blunami as well. He talks about how he enhanced the lighting on this older model, renumbered it, and added some weathering details.

This week’s model show-offs are a great example of how older models can be brought back to life with a new decoder and a bit of elbow grease. In today’s challenging economic climate—especially with tariffs affecting prices—model trains can get expensive. This is a resourceful way to get a high-quality model at a fraction of the cost of buying new.

Blunami works seamlessly in DCC, but our app removes the confusion of CVs and decoder setup. You can configure everything in the app, then switch to DCC operation with ease. Our decoders are full of features, so chances are, if you want your train to behave a certain way—it can! And if you’re stuck, just give us a call. We’re happy to help.

Graham runs an Athearn BNSF GP38 with a factory-installed Tsunami2 decoder. George has an Athearn GP38 and a ScaleTrains GP30, upgraded with a CurrentKeeper, Decoder Buddy, and Blunami BLU-21PNEM8. Doing the install this way gave him access to all of ScaleTrains' lights.

George had trouble consisting his Blunami-equipped locos, despite how easy we say it is. The issue? A small setup misstep. He found a simple fix and wants to help others avoid the same frustration. Watch now to learn more!

On this week’s podcast, Graham showcases his True LineTrains Railrunner, upgraded with a Tsunami2 decoder and customized lighting. His enhancements include a directional headlight, backup light, illuminated number boards, a cab light, and ditch lights.

We'll also be at the Chicago O Scale Meet in a couple ofweeks! Blunami is a game-changer for O Scalers, offering full decoder capabilities without the need to upgrade your DC layout —it's truly amazing. If you're an O Scaler in the Chicago area, be sure to stop by our booth to see Blunami in action. We'll have demo models for you to test out at the show!

You may have already met our new Support Technician, Graham, but we're excited to officially welcome him to the podcast!
