double retro for one I-TRAIN turnout
Crossing turnout need a relay with 2 change-over contacts to connect the tracks on T1 to one of the adjacent blocks, dependent on the selected route. No problem with that.
I should then have two retro possibilities from the TM44 (1B3 or 3B3) dependent on the selected route.
My concern : How to set the I_TRAIN turnout parameters to fully use this double opportunitity ?
