I've built roughly 3000 blocks worth of underground railway in my Survival game. There are stations along the way, near interesting features of terrain that require me to press button to continue.
Considering the length of the line, the obligatory stops are becoming tiresome. Currently I've made it so that return trip bypasses the stations, but it's still not optimal. I'd like a way to choose whether I stop or continue before entering the station.
Now the simple way is to hop out of the running cart and then either chase it down or use a rider detector to dump the empty cart onto a side track. That's not very elegant though.
I tried a switch, to switch the railway track before entering the station. Problem: I approach the station really fast and the switch is small. Hitting the switch while on the move is hard, I miss more frequently than I hit it.
The stations are a bit too far apart to send a redstone signal from the start station to pick my goal.
So, are there any graceful techniques how to decide upon a turn or stop of the cart while moving in it fast?
