This is just a small number of the crates of batteries for the trains that
I observed in that room! Believe it or not, the batteries used on the
trains are "Ni-Cads", just like the batteries that you find in video
cameras and cellular phones only a lot bigger! I've never seen such huge
Ni-Cad batteries in all my life, most of which were quite a bit bigger
than car batteries. I didn't know they came in sizes that big. I had just
assumed that batteries on the train were in the lead-acid family similar
to the batteries used in automobiles. Evidently these Ni-Cad batteries do
suffer from the same "memory" problems as the smaller Ni-Cads. That is,
they should be completely discharged before a full recharge or they will
start to hold less charge.
The photos in this slide show were taken in the mid-1990's
by Steve Grande on his Amtrak travels throughout the nation.
The size of the photos is purposely smaller as disk space
was expensive and download speeds were slower at that time.
