Model Information: Covered hoppers are designed for carrying dry bulk loads, varying from grain to products such as sand and clay. The cover protects the loads from the weather. Similar to an open hopper car, covered hoppers tend to contain 2, 3 or 4 separated bays. Each of these can be loaded and emptied individually, with access at the top to load the materials and visible chutes at the bottom for unloading.
Hoppers with 2, 3 or 4 bays are used for different purposes: 2 bay hoppers are used for the most dense loads (such as sand), while 4 bay hoppers are more suited to lighter loads. This is due to axle load limits, for example dry cement is very heavy in bulk quantities and a 4-bay hopper of sand would be very likely to exceed these limits while also having problems with increased strain upon the central span. By trading off cubic capacity 2 bay hoppers are able to transport these heavy loads. As technology has advanced, some of the heavier loads formerly assigned to 2-bay hoppers have been assigned to larger, more efficient 3-bay hoppers.

Road Name History: Golden West was a financial invention -- SP wanted to get capital equipment off the books but the railroad needed the cars. So a corporation was invented that used borrowed money to "buy" the cars, refurbish them, and lease them back to the SP. In the long run this is basically a transfer of wealth from the railroad to the investors, but in the short run it helped the railroad by providing working capital. The UP ended the whole deal as soon as it could and that is why everything is reverting to original ownership.
