This episode runs about 71 minutes and opens on a card reading "Episode 93" and "Debugging Trains & AMA." Basket picks up the question from the to-do sign left at the end of the last episode: why doesn't the first cart at Basket Station get any engine tokens? Late in the stream, Basket also answers viewer questions while chopping trees.
The missing engine tokens
The tokens are there after all: "There's lots of engine tokens." They're just stuck in the hoppers. Basket had powered a block to stop one hopper, and that power was also holding the tokens back: "why did I think that would work." So the line gets rebuilt to run the other way, one hopper becomes a plain block, and the tokens go back into the system. A new request for South Port Hypermine Station brings a cart with engine tokens this time. "We have resolved that problem."
A loader for chest minecarts
The next to-do item is South Port Hypermine Station, which is low on chest minecarts. Basket rides out to it and starts on a refill machine in the basement: a repeater clock that fires a dispenser loaded from the side with chest minecarts, meant to stop once there are enough carts in stock. A lever sets the rail so new carts go the right way, and powered rail keeps them from getting stuck. A handful of test carts drop onto the line and end up in the right spot.
To refill it without going downstairs, Basket crafts a pile of hoppers and snakes a line up through the floor to the main room. It ends in a chest between the destination buttons, with a sign: "Extra CHEST Minecarts." Basket fills it with fresh chest minecarts.
Through Basket Station to Iron Farm
Next Basket checks how this station is programmed for Iron Farm: Intersection 2 south, Intersection 5 west, then an Intersection 3 east token. That last one isn't needed, since the intersection already defaults into the station, so Basket breaks those tokens out. Then comes the test. "Moment of truth: does our train continue forward? Yes." The train rolls straight through Basket Station and on to Iron Farm, and the caboose resets the intersection behind it.
The line still needs work: torches down the middle, bridges with no supports, a spot for a future intersection. At Iron Farm Station there's a pile of carts. Its safety mechanism is down below and still needs a line up top, but there isn't enough material for that yet.
The to-do list grows
Back at Basket Station the basement is crowded with carts and cabooses. Basket drops off redstone, labels storage chests, and sets one open chest as a drop-off for spare engine and caboose tokens. New to-do signs go up: add droppers at South Port Hypermine Station and add lots of chest minecarts there.
Trees and iron
To make more chests and chest minecarts, Basket goes to chop trees and replant the saplings, answering viewer questions the whole time. There's no ender chest at the station to stash things in, so one more sign goes up: "Add Enderchest ATMs to Basket Station Mall." Basket rides to Iron Farm Station, collects the iron and crafts it into blocks, with the chest minecarts for South Port still to make when the stream ends.
