This engine has been tested extensively to examine the impact of changing motors similar to the motor test bed series and it has been used to evaluate the impact of various electronics modules.
This is one of a series of tests being performed with and without electronic modules. The purpose in this series is to understand some significant performance differences that have been observed when a module is in the circuit. These electronics can take many forms. The most obvious is a DCC decoder. It can be as simple as a light card. It can be as complicated as a sound system added to a decoder or something else. It may be one of the new DC control modules.
