One of the constant complaints I get about Train Sim is that the locomotive sounds need improvement.  In the past I have been hampered by the 50 MB file limit in the Google Play store (audio files take space).  I have also had a hard time finding a sound engineer that was able to come up with these realistic locomotive sounds.

Fortunately both of these challenges are now solved.  So my focus for the next Train Sim release is to add realistic and unique audio for each of the 41 Trains in Train Sim.  I have already implemented several of the new audio effects and they sound great.

Stay tuned for more info.
