Shachiku Train

Shachiku Train (社畜トレイン) (lit: Corporate Slave Train) or Company Train Is a unique Prophecy T-Spin Double method which is mainly used on a relatively flat terrain. This form mainly uses S one column away from a wall and an L hanging on top of it in order to create a T-Spin Double which would then be immediately followed by another T-Spin Double. This setup was developed by Japanese players and The English name for this setup comes from Malady's 550 slides of T-Spin guide.

Generic Structure
As long as S has a place to be dropped with at least 2 blocks high wall on one end of S and a single gap on the other end of S before it hits wall, this technique's generic structure is always possible.

Variations, Other Uses, and Comparisons
As mentioned before, this technique is always possible as long S has a place to be dropped. Even though it's possible, doing it over a 3-wide hole is inefficient in most cases because the player is forced to make an unconventional overhang in order to achieve the second T-Spin Double.

If L has a place to be dropped on, players could drop the L first before spinning in the S later.

S and L could be substituted by other blocks. As long as it still maintains the same shape as the generic structure, it is still possible.


 * Compare the 4th example of the Company Train's variations above with Kaidan Setups (both L and J are just swapped) (credit to kazu).


 * Compare the 5th example of the Company Train's variations above with Cut Copy (S is just shifted one column to the right).

For terrains with 4 columns wide and 2 rows deep hole, creating the variation of Company Train below is possible. One could place down the floating S and the overhang before spinning J in.


 * Compare the example of the Company Train's variation above with STMB Cave (O base is used instead of J).

If possible, making the overhang for the second T-Spin Double on the other side of the build before the T for the first T-Spin Double comes could help on executing a much faster attack.

Diagonal shaped holes below Company Train could be used to make three or more consecutive Company Trains. The downside to this is that this variation requires a lot of Zs on demand and might block the Tetris hole (if there is one) located below the build for a few bags.

Company Train could also be used as a direct follow-up to a T-Spin Triple.

Company Train could be used along with Donation T-Spin Double for effective usage of pieces.

Instead of directly doing the second T-Spin Double, repeating another Company Train is also possible and it also maintains a clean stack. In theory, this could be continued infinitely. But in practice, this requires a lot of S and L on demand. This shares the same principle as Mechanical TSD v3.
