This stream archive runs about an hour and opens on a card reading "Hypermine Stream Archive" and "Train Dropper Array", with no episode number, so the number here comes from the playlist. Basket is back under Basket Station, working on the bottom half of the destination picker, where droppers will spit out the tokens that tell a train where to go.
Will the tokens get stuck?
Basket would like a lot of ice for this part, "ideally packed ice," but settles on regular ice so as not to be a resource hog. Then a new worry comes up. The tokens will drop out of the droppers and fall, and there is a lip on the way down. "I wonder if it'll ever get stuck on that lip there."
Rather than guess, Basket pops into a creative test world and builds a small copy out of orange blocks: ice on the bottom, water on top, the lip and a wall at the end, counted out to eight blocks. Then a whole stack of items goes in. "Oh look at that, none of them fell into the spot that I'm worried about." The design stays as it is, and Basket heads back to the server.
Hunting for ice
Back on Hypermine there is still no ice to build with. Basket asks in the in-game chat, "you guys have an ice tray at all?" Cassildz answers "not really, I'm collecting from a mountain," and Twinkles adds "There's none that I know of :(". Basket's reply: "I'll make an ice tray someplace :D". Cassildz also asks where the portal to the End is, and Basket points to the nether hub, where there should be a sign at one of the four exits.
A dark room with doors
Without ice, Basket works on the structure around the two chutes instead. These will run under the droppers, collect the tokens and bring them together where they get loaded into the engine cart, like at the small stations. Basket adds a catwalk, a ladder up to the top, and doors with buttons so there's a way in for maintenance. The idea is to keep this space dark. Half slabs go in over the openings so no light gets in to melt the ice later. Basket starts with iron doors, then wonders if wooden ones would be simpler.
The pistons in this level pop up when they fire, so each one gets a temporary block, then a slab on top, then the block underneath comes out. With no repeaters left for the bottom spots, torches go in on every other one to stop mobs from spawning.
Blocks or furnaces on the hoppers
Over the hoppers, a viewer suggests furnaces to cut down on lag, and the chat goes back and forth on it before landing on plain solid blocks working just as well. Basket goes with blocks: "I did furnaces in the other one," and those took eight cobble each. Then the old work platform comes out and a solid floor goes across the whole thing, with a gap left open to reach the redstone on top of the droppers. The floor should also stop any light that might come through the hoppers.
Out of blocks again
The smooth stone runs out partway, so it's back down to the storage for more. Basket fetches a stack of droppers, finds the one spot that still needs a sticky piston, and puts in a ladder after first blocking the way up so well that mobs couldn't get there and neither could Basket. In the chat, Cassildz goes "afk at the blaze farm."
To finish, Basket climbs down for a look at what's left: the two chutes at the bottom still need their water and ice so they can push the tokens to the middle and load them into the engine. That's for a future stream. The credits run to the end of the video with no gameplay after them.
