Cable cars replaced horse-and-buggy transportation, but trolleys (powered
deals) replaced cable cars in many places. Today, San Francisco is the
only city still running cable cars. The
Cable Car museum has been around since 1974 or so to pay tribute to
this little guys with the bells on top.
The entrance is at the corner of Mason and Washington Streets in
San Francisco.
Each car has two sets of wheels, including two wooden brakes (yes,
wood, even today).
From the 1870s, No. 54 is from the Sutter Street Railway line (one
of eight running back then)
There are four powerful engines that move the cables at a constant
9.55 miles per hour.
When moving uphill, the cars are tugged along the cable line; going
downhill, they sort of free-glide.
This is one of those signs you won't find anywhere else in the world.
