I have included a team track in each of my layout's towns, as they can handle almost any type of car. While I'm modelling the late '30s, this would be fairly typical of what you might find anytime between the early 1900s and the mid-to-late-'50s:
Loading or unloading directly between rail car and truck (in some small towns, this was done at a level crossing, with the train pausing while the transfer took place - easy to fit into almost any layout):

The same operation could take place across a platform - this could allow unloading to take place while the truck or wagon was not present, freeing the empty car sooner. The ramp was useful for unloading machinery or automobiles, too:

Bulk commodities, such as coal or gravel could also be received:


And by reversing the machinery, the same type of products could be shipped out.
For larger and/or heavier items on flatcars or in gondolas, some yards had an overhead crane on-site:

This simple building serves as an office for the Agent, and also as a lunchroom when other yard employees are on duty:

In some smaller towns, there could be a shed of some sort where lcl shipments could be stored for later pick-up - this would allow the car to move on to the next town down the line:

Here is a couple of views of the larger team track area, in the centre of the photo:

And here, at far right:

As you can see, it doesn't take up much room.
