This episode runs about 73 minutes and opens on a card reading "Episode 99" and "Debugging Freight Receiving Logic." At the task signs in Basket Station, Basket lists the options and puts it to a vote. Number two wins: "Debug freight train arrive at Basket Station." Basket warns it "might be difficult."
Faking an arrival
The station is meant to split an arriving train. The engine and caboose get emptied and stacked again, passenger carts go back into the system, and freight carts are sorted off to their own area. Last time, not every freight cart ended up where it should.
To test that without riding somewhere and back, Basket uses the fact that "nobody's on the server." A rail under the station comes out, so a train with no destination tokens loops straight back and arrives at Basket Station again. Basket requests a train, strips the destination token out of the engine, adds chest minecarts holding three wood each as freight, hits the button and runs downstairs to watch.
Carts that fall too far
The first run sorts the engine correctly, but the next carts drop onto a rail, lose their momentum and roll down below first. A few blocks to make them fall straight down fixes that. The bigger problem: the caboose lands in the freight area with the freight, when it should go off to be emptied.
The items are wrong too. The sorter grabs one item from each cart to tell whether it carries freight, then hands it back. The carts move on too quickly, so one cart comes up short and the stray wood turns up in the caboose. Basket lengthens the loop with a few more blocks to slow them down, and the next test has three logs in each freight cart: "it's rearranged them slightly, but that's fine."
A look at the test world
To answer a viewer's question about where the freight goes, Basket briefly loads a test world with a full freight yard design that "will eventually maybe exist underneath Basket Station." Trains arrive into separate spots, and a lever empties a train's carts into a chest. It isn't a sorting system: everybody is responsible for their own train. Basket also says the design doesn't use shulker boxes, since Basket has none on the server.
Chasing the caboose
Back on the server, the caboose keeps going straight into freight. Basket fixes a counter, then tries more spacing between released carts, and finds the timer Basket changed sets how long the release runs, not the gap. One test comes up a cart short: a cart got stuck mid-ride when Basket logged out to the test world. Another time a cart switches and then goes backwards, which throws the count off by two: "That's not how Minecraft works."
Basket takes the slope out of one rail and trims the delay one tick at a time. On the last run the two freight carts go straight and the caboose turns off to be emptied: "Amazing. Amazing. Yes!"
Putting it back
Basket puts the station rail back so real trains leave properly, fills in the hole Basket kept nearly falling down, puts the spare caboose and intersection tokens away, and takes down the "Debug freight train arrive at Basket Station" sign. Only a few train shapes were tested, but Basket's verdict is "good to go." For now the freight carts end up in a temporary spot in the basement until a real freight area is built.
