Splitting the power base from its track piece is another option.  It gives you better options to position the start/finish and allows you to put the controls and throttle sockets where it suits you.  Cat5 cable is good for the data cables but make sure the power cables are thicker.

I did this so the APB is in the centre of the front edge of my track table but on a unit underneath the table.  The start/finish is about 2 metres away at the end of my long straight.
