Minecraft – How to make Chiseled Stone Bricks in Minecraft

East-facing stairs break into the second type of plain stone brick, due to a glitch.

Some blocks hold a data value, to determine things like the hue of wool or the height of wheat. All stairs use a data value of 0-3 to determine which direction they face:

• 0: South
• 1: North
• 2: West
• 3: East

But stone brick uses this data value to determine type:

• 0: Normal
• 1: Mossy
• 2: Cracked
• Anything else: Not normally obtainable, will default to normal

When you smash a stone brick, it retains its data value, which is why smashing stairs creates different stone bricks. The type of brick corresponds to the direction of the stair it came from. Because there are four cardinal directions and only three types of brick defined, the fourth type of brick just looks like normal brick.

As far as I understand your question, you have trouble with the track going trough the door...

Here is a screenshot of my setup, first you switch over to the new track, then you go trough the 'door', but by going down under the door block the track doesnt break and just creates a slope whenever the door is open, this would work in both directions.

Also as often happens with these timed things, the doors or track switcher might not stay open long enough, here is a way to lengthen that. (This is my own design, not all that compact, but the only thing that makes sense and works for me)
