From the project

Model 2nd Generation Diesel Locomotive Control Stand

This is a model diesel locomotive control stand (more or less typical of a 2nd generation diesel locomotive).

2ndGenLocoControlStand.dxf, 2ndGenLocoControlStand.gcad, and 2ndGenLocoControlStand.tcl relate to the 3D model of the front panel (based on a Hammond Manucafturing RL6685 enclosure).

The ESP32ControlStand directory contains the ESP32 (TTGO-T1) based design, the electronics are in KiCad form (Version: 2013.06.11). The ESP32ControlStand/ESP32ControlStand_Node directory contains the OpenMRN code (C++, Arduino style using the OpenMRNLite library).
