Freight house

The track adjacent to the freight house is called a house track. Boxcars are positioned on the house track with their door adjacent to the freight house door, so a portable short steel bridge can be positioned allowing wheeled vehicles to move between the freight house and boxcar while loading and unloading. Some freight houses use several parallel house tracks by carefully positioning boxcars on the more distant house tracks adjacent to boxcars on the closest house tracks so boxcars on the inner tracks serve as a bridge to boxcars on the outer tracks; but providing a platform between the house tracks allows more flexible positioning of boxcars on the more distant house tracks.

Larger communities might have separate freight houses for inbound and outbound freight. Railroad employees in the outbound or receiving freight house take freight in through the doors on the driveway side; and inspect it, weigh it, and handle billing and marking before moving it into boxcars on the house track. Inbound or receiving freight houses are typically wider to allow temporary storage of freight unloaded from boxcars before the customer is ready to load it. Both functions are combined in a single freight house which is the more common installation in smaller communities.

Most freight houses are single-story structures, but some have been built with multiple levels where land values are high. Upper floors may be used for storage, and the ground floor may be used for freight transfer to trucks and wagons, while elevated or subterranean house tracks serve a different level. Some rail hubs have special freight houses dedicated to sorting and transfer of LCL freight into different boxcars so freight originating from different locations may be placed in boxcars for similar destinations.

Although early railroads shipped a large percentage of freight in LCL quantities, most rail freight now moves in bulk quantities directly between mines, ports, and industrial sidings. Freight houses which were once among the larger structures in their communities have found a variety of uses when no longer needed for their original purpose. Others have been preserved as historic structures:
