It sounds like the club is attempting to purchase a new TIU Rev L in time for the Oct 11 AMRE show. Excellent! We need second TIU as a swappable spare for sure.
I'm willing to loan the club my Rev L TIU for the show if the club's new one doesn't arrive on time.
I recently decided to have both 2 rail and 3 rail trackage and Command operation on my home layout (best of both worlds!) and so purchased a brand new MTH DCS Rev L TIU. It has the latest software revisions and runs both Proto 2 and Proto 3 engines very well.
