I posted this query because the drawing,though probably correct seemed troublesome. The need for crossovers there was obvious since SEPTA trains terminated there inside or outside of north platform, and then had to crossover to other side to south platform. outside or inside platform track? Conversely NJ Transit terminated on southbound platform, inside or outside track? Thence it had to crossover to north platform, inside or outside track to begin new journey northbound.
Under these conditions a set of double slip switches or simple crossing tracks would make sense. HOWEVER it creates havoc for high speed train travel on Amtrack thru tracks.
i was curious if I was alone on wondering how this worked or if it did not work long term.
