In case you're interested here's a video and some photos from converting a GP20 to TMCC, RailSounds, LED's, and electro-couplers. Click here to see the video on YouTube and here to see more photos with captions. Thanks.
What does it cost to have you do it?
That depends on the type of engine, the number of modifications desired (TMCC, RailSounds, LED’s, electro-couplers, can motor, etc.), and the condition of the engine to begin with (i.e. will it require repairs before conversion work can begin). I gladly provide estimates. Please email me at firstname.lastname@example.org so we can discuss what you want done. Thanks. I charge $30.00/hour plus parts and shipping at my cost.
