The real issue here is current draw..
in the authors comment, I see no mention of isolated individual track blocks…
so, the current draw creates the heat-which is a byproduct of the transfer of energy.
To reduce heat, reduce the current draw
the first step should be to reduce the distance the current must travel on the rails, not just the distance on the feeders.
it is my determination that even a simple track layout that runs more than one locomotive, should be divided into equal isolated individual track blocks and fed with feeders in parallel.
why?
Because as you add loads, which are heat dissipators, the total resistance decreases, as does the heat.
And the benefit of parallel wiring, to smaller track sections also decreases the force-or voltage, required to overcome the inherent resistance of the track and wire; this also diminishes the heat byproduct.
This animal we call electricity, has an amazing talent when sent through parallel paths….the total resistance of the total circuit will be less than lowest value of the smallest resistor in the paths.
That decreases the heat byproduct
