Neither. At 100 miles an hour a clearance of 2.54 inches would probably
create a venturi effect sucking you into contact with the structure above.
Secondly, since most tunnels are arched, if the pole is mounted above the
tracks instead of on the railroad cars center line, the maximum clearance
will not apply.
Thirdly, railroad cars traveling at 100 miles an hour tend to sway from
side to side.
The point is that the metric system gives the illusion of a precision which
is totally lacking in real life situations.
