026 * Frame for edit of rolling stock. The common elements are: road, road number,
027 * type, blocking, length, location and track, groups (Kernel or Consist)
028 * weight, color, built, owner, comment. The edit engine frame currently doesn't
029 * show blocking or color. Engines and cars have different type, length, and
