AC track voltage regulation options

Tangential to my “balky Pullmor motor” thread recently, diverged into the problem of track voltage drop under ordinary train loads (heavy trains up to 4 AC motors is specific instance), and the search for voltage management/regulation solutions.  In my case see about a 4 volt drop in the voltage at transformer outputs with both Z4000 and Mainline Industries “The MAX” heavy train transformer from former business Davis Trains, now out of business.  This drop makes AC Pullmor motors slow dramatically so that a trip around the mainline with line drops of only 1-2 additional volts goes from racing to crawling.  Cranking the transformer setting to get loaded voltage of 19v exposes Lionel boards to 22v+ potentially when anything happens to stop the current draw.  There is no “Cruise Control” option for AC motors, and for can motor engines the cost and installation time to add Cruise Commander M to all of my locos affected by similar but lesser speed variation makes it worth considering fairly costly options to stabilize the track voltage under load. This current post is placed here in a new thread, seeking information from others with knowledge:

Have had no luck finding a low voltage ac full sine wave voltage regulator device.  However for an industrial transformer option, here is an interesting possibility with a $980 price tag for the enclosed version, about $200 less if you buy open and make your own enclosure for it.  The key spec for this specific ISE product model group is an output voltage drop of only 0.8v at full 15a load when the output is set to 20v (would be ~same at 19v.)  Curious about other manufacturers/sources/prices if someone has knowledge.
