Subsequent to my last post, I am going to continue to explain about the Keio-Toei direct operation that marked the 40th anniversary on March 16th of this year. This time it's the Keio story. Keio Electric Railway offers their 9000 and 5000 series trains for direct operation between the Keio and Toei-Shinjuku lines.
The 9000 series was launched in 2001 to replace the old EMU 6000 series. In the first stage, 8 sets of 8-car trains (64 cars) were built by Nippon Sharyo and Tokyu Sharyo. A new group named the EMU 9030 series was then commissioned in the second stage in 2006. 20 sets of 10-car trains (200 cars) were built by Nippon Sharyo. The 9030 series also belongs to the 9000 series group, but it is specialized for the Keio-Toei direct operation. The 9030 series has an IGBT-VVVF (Insulated Gate Bipolar Transistor - variable frequency drive) inverter electric control system made by Hitachi.
On the other hand, the 5000 series debuted in 2017 as a high-end commuter train. 6 sets of 10-car trains (60 cars) were built by J-TREC in 2017 and 2020. This model has multi-purpose seats, which the conductor can change from long seats to cross seats using a remote control system. The cross seat mode is applied when it is operated as the "Keio Liner" train on the Keio line.
Celebrating the 40th anniversary, Keio currently displays a special memorial plate on the front of 9740F of the 9000 series.
