Milwaukee Electric crane car L-6 had one of those big trolley wheels when
the original East Trolley Trolley Museum acquired the car from Lakeside
Power Plant.

The present East Troy group refitted the car with a shoe some years ago.
Since Milwaukee Electric was an early proponent of shoe use, it seems
surprising that this particular unit retained a trolley wheel into the
1970s. This crane car had a single trolley pole, so perhaps the theory was
that the car could be jockeyed back and forth while working with a lesser
chance of damaging the pole or overhead by using the large wheel(?) I'm
guessing here....

before. Why Carbon ? You do not need wire greaser cars. The carbon shoes do
the lubricating supposedly. They did wear out faster than the brass ones
used elsewhere but before the carbon shoes,all cars had wheels. The largest
wheel I ever saw were the one on TCRT on Mineappolis ,when Seasore recieved
their Gate Car from them in 1950's. The thing was 9 or 10 inches in
diameter. These of course didn't wear out as fast as the smaller ones did.
Never saw another system that used such large ones. Maybe somebody knows of
one ?   cheers rogertrolley
