This week, we hear from G4, aka Doctor G4, Notch 11, aka John Gardiner IV. G4 is a long-time friend of the podcast and a valued member of the AML Nation. In this sprawling conversation, we hear about G4's travel across nearly the entire Amtrak system from coast to coast to explore and photograph Diesel Multiple Units (DMUs). We discuss G4 biking across commuter rail systems, capturing thousands of photographs to support a future article for Railroad Model Craftsman.

There's also discussion about European and American DMU prototype equipment, currently available as scale models from Europe, and all the while, G4 does his best to absolutely annoy the Evil Overlord. So sit back, with a big bowl of shredded light rail schedules, slow down your podcast player's speed to 0.75x, and buckle up for a fun conversation.
