Hi, everyone. I have a K-Line K3790-4015S Big Boy that I want to possibly perform some upgrades on. As is, the engine currently has TMCC and Railsounds.
I have been looking at various ERR upgrades in hope of gaining cruise control and better sound, as well as fix a few issues I’m having with the engine.
From the attached pictures, you’ll notice the smoke unit is removed. I also want to replace it with a better one and potentially add puffing synchronized smoke. Perhaps through GRJs super chuffer.
I also have an intermittent issue, where the engine refuses to run in reverse. I have already replaced the DCDR.
Finally, my rear elctrocoupler won’t work, despite replacing it with one from traindoctor and the sounds sometimes lose communication with the engine, despite replacing the tether with one from traindoctor.
Overall, I want to “revamp” this engine and get it running better than it ever has. As far as ERR upgrades go, I’m not sure what I need, given that this engine already has TMCC equipment. Can I possibly re-use some of the old equipment, or should I gut the engine and tender and start fresh?
I’ve done my best to take images of the engine and tender in their current configurations. Things like the chuff switch, I have no idea where they are located or how they would factor into an ERR upgrade. The tether also has 6 pins, but appears only 4 wires are used. If any of you want a picture of a different angle, I can provide it.
Any advice is appreciated.
