The iE305 series,[2] also known as CLI-225 series,[3] is an electric multiple unit (EMU) commuter train type operated by KAI Commuter. This EMU is designed and manufactured by Industri Kereta Api (INKA) in Madiun and Banyuwangi, East Java,[1][4] in collaboration with Japan Transport Engineering Company (J-TREC).[5] This EMU uses technical specifications determined by the Directorate General of Railways (DJKA) of the Ministry of Transportation of the Republic of Indonesia.[4]

This EMU utilizes components sourced from both domestic and foreign production. In the electrical and equipment section, it uses components produced by Toyo Denki Seizo [ja].[6] As for the braking system, it uses components produced by Nabtesco.[7][8]

The iE305 series has a formation of 12 cars on each trainset.[9]

History

KAI Commuter and PT INKA signed a contract for the production of 16 trainsets or 192 units of the iE305 series on 9 March 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 10 March to 12 March 2025, initial testing was conducted at the INKA factory in Madiun and Japan [9]

On 17 March 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 16 March 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 phases, with each phase comprising six cars, pulled by a locomotive that is accompanied by several unmanned passenger cars to aid in braking.

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

In the afternoon of 18 March 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 19 March 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 16 April 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 21 April 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 22 April 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 resumed its trial run in Jabodetabek. The trial run began on the Bogor Line on Sunday night, 27 April 2025.[15] The trial was conducted by KAI Commuter together with Toyo Denki Seizo [ja] and Nabtesco.[8]

These trials follow the guidelines of the Ministry of Transportation Number 49 of 2023 concerning Standards, Test Procedures, and Certification of the Feasibility of Normal Speed Trains with Self-Driving. The tests consist of Design and Engineering Tests, Static Tests and Dynamics Tests.[16]

On 16 December 2025, the first and second trainsets of the iE305 series officially entered service, with a public trial run carrying passengers on the Bogor Line.[17]

Formations

Each trainset in the iE305 series comprises 12 cars. This configuration features two driver cabins situated in the first car and the twelfth car (the final car). These two cars are non-motorized and are classified as trailer cars with driver cabins (Tc).

Meanwhile, the other trains are divided into several types, namely:

  • M1 and M2: Motor cars.
  • T1, T2, and T3: Trailer cars.

In general, the standard formation configuration of the iE305 series is arranged as follows:
