Model Railroading > Looking for Bachman Sound Module

Morning Everyone,
I have a Bachman 50 ton two truck Climax locomotive that runs and performs beautifully. Would love to add the drop in sound module but cannot find one anywhere.
I spoke to a Bachman Rep at the Denver Train-Show and he said that they have no plans to produce anymore. Soundtraxx was the one who built and supplied Bachman.
And  they have none. I am appealing to the Train Orders Model Railroad community to see if anyone or any other source has this sound module.
Bachman part No:44956.

Bachman Climax 50 ton two truck.
Before someone suggests it, the 70 ton mod will not work in the 50 ton.

If anyone can help me out- PM me. 
Thanks in Advance,
Jim Leonard
