Single track monorail

[Lego Otaku]

LEGO Monorail system used wide track to provide base for the wheels on the bogies, and many people have created custom monorail system using bricks but the width of the track relative to the monorail vehicle is pretty wide.

Hypothetically could one use the old train rail (1x16 stud) and make a train oh around 6 stud wide and using gyroscope to maintain balance work?

in TV series Digimon 4th season, these trains were used a lot throughout the show. Their wheels only touch the rail and I'm guessing gyroscope could help work but I dunno.
