History

KAI Commuter and PT INKA signed a contract for the production of 16 trainsets or 192 units of the iE305 series on March 9, 2023.^[4] The delivery of the entire iE305 series will be carried out in stages from 2025 to 2027.^[10]

The first trainset of the iE305 series was completed in early 2025. From March 10 to March 12, 2025, initial testing was conducted at the INKA factory in Madiun.^[9]

On March 17, 2025, the first trainset of the iE305 series was delivered from the INKA factory in Madiun to the Solo Jebres EMU Depot. Just a day before on March 16, 2025, the EMU was for the first time went outside the factory area and was exhibited to journalists at Madiun Station.^[9] The Solo Jebres EMU Depot is a EMU Depot owned by the DJKA Railway Maintenance Center and managed by KAI Commuter.^[11]

The delivery of each trainset is carried out in two stages, with each stage consisting of six cars and being pulled by a locomotive accompanied by several unmanned passenger cars to assist with braking.

iE305 series conducted a test run on the Yogyakarta Line passing Delanggu station.

In the afternoon of March 18, 2025, the EMU underwent a short test run around Solo Jebres station. This short test run was carried out for the train driver to adapt to the train controls.^[12]

In the early hours of March 19, 2025, the iE305 series for the first time underwent a full speed test at 120 km per hour on the Solo Jebres-Lempuyangan section of the Yogyakarta Line. Later in the afternoon, the test run continued on the Solo Jebres-Klaten section.^[12] The test run was carried out by INKA, KAI Commuter and PT Surveyor Indonesia as consultants.^[9]

On April 16, 2025, the first trainset continued its delivery from Solo Jebres Depot to Depok EMU Depot via Purwokerto, following the trial run on the Yogyakarta Line.^[8][13]

On April 21, 2025, along with the SFC120-V series, the iE305 series was sent from Depok EMU Depot to Manggarai Station in preparation for the event commemorating the 100th anniversary of the first railway electrification in Indonesia on the next day. On April 22, 2025, the iE305 series was exhibited at Jakarta Kota Station, alongside the ESS 3200 class, SFC120-V series and various other EMUs.^[14]

After previously being exhibited, the first trainset of the iE305 series began to continue its trial run in Jabodetabek. The trial run began on the Bogor Line on Sunday night, April 27, 2025.^[15] The trial was conducted by KAI Commuter together with Toyo Denki Seizo [ja] and Nabtesco.^[8]
