This uses version 2 of my minecart detector loop, it's much more stable (haven't seen it break yet) at the expense of only working in one direction, so the connections have to be made more carefully. It also oscillates slightly faster, meaning the detection circuit can take a little bit less room. The primary control room is 11x13x3, and I'm optimistic I can fit a second launch and return ramp in that space.
Also featured here is a very nifty trick (if I do say so myself) for detecting the presence of a player in a minecart, without disrupting the momentum of the cart or using too much vertical space. It uses a very short boost to get the cart over the gap in the track where the stone pressure plate has to sit, and works beautifully. There's another trick on the opposite side, which uses the fact that a cart will depress a wooden button when it's cornering around a bend. Although there should never be a reason for a cart to start traveling the wrong way, this will turn it around by feeding it into the cart return system.
What needs to be finished now, apart from the dispatch rail for the southbound side of the track, is a call-ahead system that sends a signal to the next station up the line to release its cart, whenever a player is riding towards it. That way, the carts will trade places, and the whole system will be ready for the next passenger much more quickly. The real catch with this, and the reason I can't just send a couple of long signal lines back and forth, is that I need the unoccupied cart from that station to not get routed back to its own holding loop. I'm pretty sure I have a way around this that won't take too much space, though.
On the subject of space, the station footprint right now looks like this:
- [*:1aeherww]Boarding Platform - 15x11x6 (counting the lights in the ceiling)
[*:1aeherww]Control Room - 15x11x6 (including wiring in the ceiling and floor; directly below the Boarding Platform)
[*:1aeherww]Access hallways - 5 spaces of padding on each side of the platform, 3 on top
[*:1aeherww]Connector Track - 18 spaces on both sides of the platform leading out to the next station.
[*:1aeherww]Total Area - 51x21x15 (Main station takes 15x21x15, each arrival/departure track takes around 18x15x7)
