Asking about the thought process if I may -- if there is a solid Free-MoN presence, then what is the appeal of T-Track? Is it because the modules are easier to build (unitrack, no legs, ....?) I suppose a Free-MoN module could be built with Unitrack, if someone really wanted to [1]; tho I am not sure if that saves all that much time/effort.

[1] yes i know the standard calls for Code 55 flextrack or handlaid track; otoh i don't see a technical reason why UT would not work, if it were cut square/flush to the endplates.
