INKA CC300

The INKA CC300, also known in the Philippines as the PNR 9000 Class, is a multipurpose Diesel-hydraulic locomotive owned by Directorate General of Railways and built by Indonesian state-owned rolling stock manufacturer PT INKA. Launched in 2013, it is the first mainline locomotive wholly produced by Indonesia and the first locomotive exported by Indonesia to another country, when the Philippine National Railways (PNR) received its first set of INKA CC300 locomotives in December 2020.

History
For decades, Kereta Api Indonesia (KAI), Indonesia's state-owned railway company, has operated trains throughout the country using diesel and electric locomotives supplied by other countries. However, most of these locomotives were designed without consideration of Indonesia's tropical climate, and as such, these locomotives are vulnerable to flooding during the monsoon season. In 2009, KAI and Ministry of Transportation began cooperation for the development of a new locomotive that would be built in Indonesia and designed to withstand flooding on railway tracks.

State-owned rolling stock manufacturer PT INKA was chosen as the manufacturer of the locomotives. The company spent around 20 billion rupiahs for each locomotive, with the Indonesian government contributing 30 billion rupiahs for the development cost. Three units of these locomotives were built in PT INKA's locomotive plant in Madiun, East Java, Indonesia. The locomotives were launched and unveiled to the public on 20 May 2013, coinciding with the National Awakening Day commemorations.

Technical specifications
The INKA CC300 locomotive has a length of 20000 mm, a width of 3000 mm, a height of 3700 mm, and a weight of 76 t. It features double cabins that allow train drivers to switch from the front to the rear cabin without climbing down the train. The locomotive is powered by a 1864 kW Caterpillar 3512B-HD TA diesel engine mated to the transmission from Voith and can run up to a maximum speed of 120 km/h, with a traction force of 270 kN when the locomotive moves from a total stop. The braking system used on the locomotive is a pneumatic brake manufactured by Westinghouse Air Brake Technologies (Wabtec), while the master controller was supplied by Woojin Industrial Systems from South Korea. It is also equipped with a Caterpillar CAT C15 generator set so that it does not require a generator coach if it hauls a series of passenger trains. The locomotive is also equipped with CCTV cameras on both sides for easier maneuvering when reversing and to monitor coaches being hauled. According to Agus Purnomo, president director of PT INKA, the INKA CC300 locomotive is quite reliable as it is flood resistant and can still haul trains despite a flood height of 1 m.

Allocations
There are currently five units of INKA CC300 locomotives (CC300 12 01, CC300 12 02, CC300 12 03, CC300 14 01, CC300 14 02) made by PT INKA in Indonesia and three units (CC300 20 01, CC300 20 02, CC300 20 03) in the Philippines. The locomotives in Indonesia were placed in Jakarta (Tanah Abang Depot & Cipinang Depot), East Java (Madiun PT INKA Depot), North Sumatra (Medan Depot) & Lampung (Tanjung Karang Depot), while the locomotives in the Philippines were placed at the Tutuban Depot.

Purchase
During its launch, Purnomo said that PT INKA is looking forward to export the locomotive to other countries in need of flood-resistant locomotives. On 28 May 2018, the company signed a contract worth ₱1.4 billion (US$26 million) to supply the Philippine National Railways with three brand-new INKA CC300 locomotives and 15 coaches for use in re-fleeting its commuter service in Metro Manila. The locomotives were built in PT INKA's Madiun plant and underwent testing in KAI's railway lines before it was delivered to the Philippines on 23 December 2020. This export follows PT INKA's previous export to the PNR of two sets of 8000 class Diesel Multiple Units in December 2019 worth 130 billion rupiah (US$9.7 million) and four sets of 8100 class Diesel Multiple Units in February 2020 worth 301 billion rupiah (US$21.4 million).

Design
Unlike the first CC300s of Indonesia (CC300 12 01 - CC300 12 03), but same design as the other 2 Indonesian CC300s (CC300 14 01 & CC300 14 02), the locomotives have four windshields instead of two. The locomotives feature the Philippine National Railways logo at the side of the cab doors and in the front cabs, and the Department of Transportation located in the middle. The locomotives are painted orange.
