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.

I think the tram was built new, but the design of the body dated from
horse tram days. e.g. the driver stood at the front in the wet with no
window to keep him dry, because for a horse tram he would need to hold
the reins and crack the whip and shout whoa etc.
It seemed to take a few years for the front of electric trams to be
enclosed.

No I don't. Why do you ask?

Shame, because if you had one you could kick him in the nuts and he'd make
a bolt for the door.

Reminds me of the Cavalry regiment who had the motto "love and ride on "
When they became mechanised it changed to "Screw and bolt"

If it were just a platform, I would agree, but there are seats in the
end sections, which would have been exposed too. Also I don't recall
seeing bogies on a horse drawn tram. They add a lot to the weight, so I
would normally expect four wheels on two axles. Two axles need to be
relatively close together for the tight curves usual for trams, so that
design would have a large overhang at each end on corners. However, take
the middle bit, which has the clerestory roof and partitions at each
end, put that on four wheels, add a much smaller driver / access
platform at each end and the length seems about right.

That wouldn't be a bolt with threads on though.
