And finally, in March 1994, train series 103 was completely replaced with 112 cars of train series 207 (with their car numbers in the 1000 range) composed of fourteen sets of eight-car trains (six-car basic train with adjunctive two cars per train) deployed at Takatsuki Depot (Suita factory, a satellite of Takatsuki Depot).
そしてついに、1994年3月に207系1000番台を基本6連+付属2連の8連14本112両を高槻（吹田工場高槻派出）に投入、103系を完全に置き換えた。
