• The distance between lay-bys shall not exceed 1000 m.
• For example, a height of around 6 m above the water line can give about 100 m of bait protection.
• The first generation of these satellites needed antennae with a diameter of 25-30 m; nowadays 15-20 m is enough.

• The meteorological instrumentation should be positioned adjacent to the test area at a height of 1,2 m ± 0,02 m.
• Enclosures shall be long and narrow (for example 2 m by 1 m) rather than square to allow birds to perform short flights.

• The distance between adjacent wheelsets must not exceed 17,5 m (16,4 m for running in the United Kingdom).
• The radius of vertical curves (except for humps in marshalling yards) shall be at least 600 m on a crest or 900 m in a hollow.
• Article measuring approximately 4 m × 30 m, made up of woven strands of plant material (sea-grass).
• These layouts allow a minimum radius of 190 m without straight track between the curves and of 150 m when at least 6 m of straight track is provided between the curves.
• The planting space must not be less than 4 m by 2 m, giving an area of 8 m2 per tree.
• Vessels and convoys not exceeding 86 m in length or 22,90 m in breadth shall be able to turn in good time.
• 60 m where vessels are more than 50 m in length.
• If the system exceeds 4 m in length, then all tubing in excess of 4 m shall be insulated, except for an in-line smoke meter, if used.
• For broad-gauge track (1,668 m and 1,665 m)
