I gifted myself a "good deal" Ten-Wheeler; Greenbriar and Big Run lumber.  First entry into On30.  Remembering last years visit to Cass Scenic Railroad, West Virginia.  Also found some log cars and steam derrick by Bachman. Now to build my railroad.   Am I having fun?  YES!!

I am in the same position.  Having taken the tender apart, i judge the task of locating a decoder/speaker, modifying the tender and hope that it all works is of moderate to extreme difficulity.   I took the approach of finding a reasonably priced supplier of that same Bachmann engine, equipped with sound, and purchased same.  The tender graphics are different, I will just exchange the shell to get exactly what I want.  Too bad Bachmann does not sell replacement parts.  This will allow me the luxery of expermenting and still have my Christmas toy!
