I Know the function 8 key turns sound on or off, but is there a way to just change (lower) the volume of the sound for a Bachman GP7 using NCE power cab? I do not have the paperwork that came with the loco?  any assist is appreciated.  I am still looking on line but thought Id tap into some knowledge here. 

Just received a new Mogul Pennsy road name and like to add some engine details per a prototype Pennsy 2-6-0. I am looking for detail items to enhance the loco. Suggestion on what details to add and the manufacture that has them. 

Have a "What-I-Did" delving into an operating front coupler for the Bachmann N-scale 2-8-0

Always about what I am doing and not really how to.

Thank you if you visit

Has anyone had any luck making these run reliably?  I’m on my second one now.  The first one sat in the box for years.  I got it out last winter, installed a decoder, spent hours lighting it with SMD LEDs, and before the project was completed the motor quit working.  Took the decoder out, re-wired it for DC and yes the motor was dead, wouldn’t turn even connected directly to power.  Walthers told me they had no parts or motors.   I packed it all up in a box and put it on the shelf.
