Rail function

This data frame contains the following columns:<dl>
 <dt>Rail</dt>
<dd>an ordered factor identifying the rail on which the
 measurement was made.</dd> <dt>travel</dt>
<dd>a numeric vector giving the travel time for ultrasonic
 head-waves in the rail (nanoseconds). The value given is the
 original travel time minus 36,100 nanoseconds.</dd>
