3D Printable O Gauge Model Kit — EMD AEM-7 The EMD AEM-7 is one of the most iconic electric locomotives in North American railroading history.

Developed in the late 1970s, it was derived from the Swedish SJ Rc4 design and built by Electro-Motive Division (EMD) for Amtrak to modernize its aging electric fleet.

Between 1979 and 1988, a total of 54 units were produced, serving not only Amtrak but also SEPTA and MARC.

Known for its reliability, efficiency, and distinctive boxy design, the AEM-7 became the backbone of Amtrak’s electrified services in the Northeast Corridor for over three decades — earning the affectionate nickname “toaster” among railfans.

🧩 About This Model Kit This is a 3D printable model kit of the EMD AEM-7 designed for O Gauge (32 mm) tracks.

It is compatible with Lionel, MTH, and also with the 3D printable OS Railway tracks created by depronized.

The locomotive is battery-powered and can be controlled via smartphone using an ESP32 microcontroller.

It is fully compatible with all of my other 3D printable O Gauge models.
