First you are on rsv for your own equipt. and domicile. You could possibly
be given a trip from a broken 900 if your a 200 driver and vice versa. Also
you could be given a trip from another DCI or mainline cancelled trip. They
do the same for us though to!
You could be deadheaded to pick up a trip in another city also or a maint repo or ???
They will be separate but if they need you somewhere else they will arrange transport to get you there by AC or Taxi or Limo.
Line holder or not you will begin trip in domicile, first leg could be by taxi though.
