Care to tell us what this nightmare of complicated design is? A lot of
us would be very interested.

This typical design appears to be a horse-drawn vehicle converted to
electric power.

The roof has lots of tiny windows so it's not strong.
When that humungous pole with springs is added to the roof, it gets
very complicated. It has long pieces of wood held on by 18 bolts.

AIUI the main value of the clerestory roof was to provide extra
clearance for oil lamps, so there really was no need to retain it after
conversion. Indeed, as they conversion also seems to have involved
adding new ends and running gear, I am surprised anyone thought it worth
while converting rather building new.
