The Rob Walker article in current O Ga Railroading issue re: new BlueRail DCC joint effort by Tam Valley and BlueRail Trains generated interest. For someone like me with a functioning TMCC and DCS layout, and many TMCC locos, so that the handheld is a normal appendage to my hand anyway, what situations might make me want to use this new option to convert a conventional loco, rather than buy ERRCo boards from 3Rail Trains for TMCC? An example loco I have in mind is the MTH PS1 C&NW 4-6-4 streamlined Hudson from years ago, which I plan to convert, was figuring on ERRCo for TMCC and not a PS3 conversion. What would make me want to try BlueRail-DCC instead, other than smartphone app control? One thought where I have no comparative knowledge is the issue of an effective loco antenna to receive signal. The diecast tender shell of the 4-6-4 would mean ? insulating handrails or ?? for this, for the TMCC job, not sure how easy it is to get enough separation (standoff from the surface) from the metal loco or tender shell for good reception. Would that be eased in some way or work better with the BR-DCC system's small antenna?
Thanks to Ron, Rob, or anyone with thoughts on this question.
