Here is a simple page to illustrate the box car.
I measure the car body width at 91mm, height off the rails at 142, body length of 389 (40 3/4 foot).
The photos were grabbed quickly so that there is something for you to see. I hope these give you the overall idea of the quality and detail on the model.
The springs in the truck frames are functional and allow around 2mm of movement.
The side door slides open and closes with a sprung latch.
The underneath of the frame is once more ready to take the alternative american style G1 coupler
