I think option 2 is a too big redirect for passengers going towards Kaeshar and Amazonis. Instead, the orange line can go to Swamphold and later in that direction if Jorster needs it, and a ring line could connect Jorster's area to Darvincia and Auspikitan later. Jungelot rails should be along x = -800.
I can approve this (red and orange thick lines), and you can begin construction if you want, as long as the rails obey the rules (foot height y = 49 on floor, centered on coordinate multiples on 20):
