                     Prowadzimy RegioExpress RPE23119 z Dębicy do Sandomierza. Misję rozpoczynamy w lokomotywowni w Dębicy. Jedziemy zgodnie ze wskazaniami tarcz manewrowych na bocznicę z drugiej strony stacji, gdzie przypinamy wagony do naszego składu, po czym wciągamy je w peron. Następnie jedziemy do Sandomierza, zatrzymując się po drodze tylko w Turowie. Po przyjeździe do Sandomierza odczepiamy lokomotywę i zjeżdżamy na tor postojowy, gdzie kończymy służbę. Czas misji: ok. 80 minut.
