Freight cars may be symmetrical (both sides identical) or asymmetrical:
Symmetrical cars can be assembled without worrying about which side goes where, Cars with sides that have different arrangements, or arrangements which are mirror images, have the differences designated on the erection drawings used to assemble them. I have no idea how those differences might be designated.
In the case of a kit with separate sides, ends, frame/floor and roof, consult the instruction sheet. (Mine won't be very helpful - they're printed in Japanese.)

Cars also have a right and left side. Standing at the B end, the side to your right is the right side. The side to the left is the left side. The designations in everyday use are usually to determine or report defective wheel bearings. The axle closest to the B end is number one.

Just to clarify what Jeff said, you stand facing the B end, then your right is the right side of the car and your left is the left side of the car. If you were reporting a problem with the bearing on the right side of the car and the second axle from the B end, you would call it R-2. If you have a car like a caboose that had a hand brake on each end, then the end that the brake piston was pointing to would be the B end. On heavy duty, mutiple truck cars that have hand brakes and two brake systems, the car owner would stencil one end the B end.
