+-- FLOW-TWO fixture — a SECOND export train, identical in shape to TRN-F2-EXP.
+--
+-- Run AFTER seed-import-corridor.sql and seed-flow2-export-train.sql.
+-- Idempotent.
+--
+-- The multi-train scenarios (TC-13, TC-14, TC-16) need two export trains on one
+-- day with the SAME pool structure, so that "which train did this booking land
+-- on" is the only variable. A second train with different pools would confound
+-- the overflow question with a capacity question.
+--
+--     35 × NW5 (CNT) + 20 × CW4 (BLK) + 5 × NW6 (FLT) = 60, at KALITY
+--
+-- Its wagon numbers (WGN-F2Y-*) are distinct from TRN-F2-EXP's (WGN-F2X-*), so
+-- the two consists never compete for the same physical stock — a shared wagon
+-- pinned by the other train's schedule would make one consist silently short
+-- and the overflow arithmetic wrong.
+--
+-- Length and pull are slack for the same reason as the first train (862.3 m of
+-- wagons behind 1000 m locos, ~5700 T behind 12000 T of pull): this suite tests
+-- SLOTS and TYPE, and a length rejection would masquerade as a pool rejection.
+
+-- 1. Its own locomotive pair at KALITY.
