This episode runs about 64 minutes and opens on a card reading "Episode 91" and "I've Been Working on the Railroad." Basket is back at the small rail station by the iron farm. The outside still hasn't been styled, so the next job is the intersection in front of the station.
The intersection can wait
Basket moves a power source over so the station's rails stay working, makes some ladders, and digs out a room under the rails, leaving a middle pillar for a ladder back up. Basket admits to forgetting how these intersections go together and plans to "cheat and go look" at another one. Counting 13 blocks out, Basket marks where the items will be grabbed and puts a hopper there.
Then the plan changes. No other lines reach this spot yet: "I don't have any paths going in the direction, so I don't have to worry about intersection quite yet." Instead Basket rearranges the rails so an arriving train goes straight into the station and a leaving one takes the right side out, with a lever and some powered rail for a boost.
Two trains and stuck carts
The first test is a ride to Basket Station. The cart that arrives has null tokens and an Intersection 6 east token, but no engine tokens. Downstairs the problem turns out to be the order split across two carts: "for some reason this one had two trains." Basket puts the caboose tokens back in the system and tries again, and this time no cart comes at all. The carts in the stack are hung up on a little ledge left for the tripwire. Basket frees them without breaking the string, and the next cart comes up right: an engine token, the destination, then a null.
Fixing the line back
The track back toward Basket Station isn't all working, so Basket follows it. Gold from downstairs becomes powered rail, gravel fills the gaps, and levers stand in for redstone to save it. The bridge goes in as plain stone bricks: "I'll style it more later." Basket matches powered rail on both lines and puts torches back. One stretch is open to the side, and "mobs could walk into it from there," so it goes on the list to make safer.
A button for Iron Farm Station
At Basket Station there is no button for the new stop yet, so Basket makes one and writes "Iron Farm Station" on the sign next to "South Port Hypermine Station." Downstairs, the cobble is already loaded, but the buffer is clogged with engine tokens and a pile of wooden swords. Basket adds a staggered row of chests with hoppers to catch the leftover junk. Tossing the swords back in turns out to be the wrong move: "throwing the swords down there is a bad idea. Got it." A new button forces the waiting carts out. Two come up, and one goes the wrong way.
Off to earn levels
The new code needs two more sets of renamed cobble: one telling the train to go south out of the station, and one telling it to go north at the new intersection. That is 14 stacks each, so 28 levels. Basket heads to the gold farm, takes off the armor so it doesn't soak up the experience, and starts on the pigmen. "As you can see there's still some bugs with my train system." The stream ends there, with the renaming still to do.
