The sound units work in both DC and DCC, and all functions are NMRA compatible in DCC mode. ### Prototype Specific Information The AC4400CW, introduced by GE in 1993 and built until 2004, is a key part of modern railroading. Many were built and are still in use. Athearn has reproduced dozens of variations of this locomotive through in - depth research and precision tooling, making the new Genesis AC4400CW its flagship model.
