Model Railroading > MTH SD70ACE Question

Where can I send the locomotive to have the horn sound changed?? I got the SP heritage unit but the horn does not match what I hear on a daily basis when the UP ACE's go by.

As I recall, there are 2 different sound files for these units. The NS version has a different horn that sounds much more like the K5LLA used on some/all of these units. Anyone that has an MTH DCS (not DCC)system should be able to load the alternate sound file and also update the firmaware if needed. This requires several additional cables and a connection to a PC. There are several online dealers such as Ulrich Models, Ligar Technologies, etc that specialize in DCC installation and can probably help you.

Go the the MTH website, and look up the closest "Authorized Service Center" to you.
