I'm playing pagroove's Electro Island route and something I'm noticing is that the trains coming out of the ICS portals are only going at 17 kph. The train goes onto a 220 kph or 270 kph speed limit sign and it still goes 17 kph, even when the driver gets assigned. I tried deleting the track between the portals and re-inserting it, nothing happens. Should I delete the speed limit signs or the portals?
