Figure 5. In the Major Tom’s rest frame (black), the vertical rail (green bold line) moves horizontally to the left, thus remains unchanged due to its position and spatial one-dimensionality. Instead, the rod moving in the oblique top-left direction in the position diagonal to trajectory, becomes contracted along that direction (bold red line segment, red arrow). In result, it deviates from the vertical and thereby from the rail
