Taken from inside one of the trolley cars they have at the Orange Empire Railway Museum in southern California.

They have everything from interurban "red cars" to the various trolleys that worked Los Angeles (and other towns). You can see the front, side and doors of another trolley through the windows of this one. The left side of the window view is the front of a Los Angeles trolley, in the green and gold color scheme. To the right are the "automatic" doors of another trolley.

The seating inside was pretty simple: a bench.
