SEED

Halloween City (r25) SEED station

SEED is a simple minecraft 1.15+ railway design developed by NastyHabits that allows you to automatically switch directions at T-intersections by holding certain food (in hand or offhand or both) that attract animals allowing them to switch track for you. It is super easy to construct and requires very little materials. T-intersection is one straight rail line with another connecting into it at 90 deg angle.

Materials required for each T-intersection:

• 1 cobweb
• 1 lead
• 1 stone pressure plate
• 1 sign
• 1 nametag (for animal)
• 1 optional water source
• 1 animal (chicken, pig, sheep (or cow), bee)
• 6 powered rails
• 10 rails
• 3 glass
• 2 redstone dust
• 5 redstone sources (torch, block to power the rails)
• 3 any blocks

How it works

You hold certain 'ticket' food in hand or offhand (or both) during your ride (you can afk as well), at intersection certain animal senses it and switches track for you automatically by walking onto pressure plate that switches the track (you can invert it with redstone torch too), when player leaves the intersection, animal gets pulled back from pressure plate into default position. Cobweb at center introduces 17 second wait time for animal to react even at serious lags.

Food tickets and animal needed to switch track:

• any seed - chicken
• carrot/potato/beetroot - pig
• wheat - sheep (or cow)
• any flower - bee

Using rabbits is not recommended since they can be triggered by golden carrots (food of choice for many), bee may need some tinkering with holding chamber design.

Look from another angle, notice holding chamber for bee on upper left
