* route0.txt
* This is a route file used by the train programme.
*
* A route is specified by listing block numbers in the order that they should
* be visited.
*
* LEGAL LINE FORMATS:
*    [positive integer] [0.0 < fraction <= 1.0] {comment}
*             or
*    [positive integer] {comment}
*             or
*    {comment}
*
* The positive integer represents the next block to visit.
* When present, the fraction represents the proportion of max speed to use.
* The comment is optional. Blank lines are legal.
*
* Apart from the route having to be contiguous (blocks actually connect to
* each other in the sequence listed), the same block can appear in the route
* as many times as desired.
*
* At the end of the route, the train programme will restart from the beginning
* and so it is expected that the last block number in this file joins onto
* the first block number in the file. If not, the train programme will exit
* with an error.
