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.
