0005  *   Extrapolation Unit:
0006  *
0007  *   The Extrapolation Unit attempts to join
0008  *   track segment pairs of different stations.
0009  *   it contains 12 Single Extrapolation Units
0010  *   to perform all extrapolations in its
0011  *   own wheel and 6 Single Extrapolation Units
0012  *   to perform all extrapolations
0013  *   in the adjacent wheel (next wheel neighbour)
