Image 3. Unloading old rails with locomotive
crane and magnet.
Image not present in the original picture-book.
This image was scanned from the panoramic
view of the main yard (Image 2).
The crane at right has a magnet designed to lift
the rails out of the rail cars, a nearly impossible
task for men to do by muscle power alone.
The electromagnet is a direct-current device
for which little current is need - just plenty
of turns of the wire coil trhough which the
current flows. The energizing cable can be
seen running between the magnet and the cab.
Another crane is in the left rear background.
