Overnight train service (Indonesia)

The Overnight train service (also known as Parcel ONS) is a freight and baggage train service that operated by Kereta Api Indonesia & KAI Logistik in Java serving the routes Bandung–Surabaya Kota and Kampung Bandan–Malang via the southern route of Java, and Kampung Bandan–Surabaya Pasarturi via the northern route of Java.

The parcel ONS service sets fares according to the type, weight, and distance of the goods.

The Overnight Services (ONS) train was first operated around Eid al-Fitr on 3 October 2007. Initially, the service was only a Parcel Delivery (BHP) service. BHP transportation is a package transportation service using a luggage cart coupled with a passenger train. BHP transportation continues to operate even though starting around 2009 the Warehouse Block Train System (SKAB) was implemented across Jakarta Storage–Surabaya Pasarturi via the northern route – then known as Parcel ONS.

Kereta Api Indonesia operates Parcel ONS trains through the southern and central lines since the implementation of the train travel chart (Gapeka) starting 1 December 2019^[1] So some passenger trains—previously carrying freight trains—are no longer coupled to freight trains. There are freight forwarding companies that collaborate with PT. Kereta Api Logistik (Kalog), such as Tiki ONS, JNE, Lion Parcel,^[2] &other shipping companies.

On 11 March 2020 PT KAI operates a central line parcel train from Jakarta Storage to Malang.^[3]

Begin on 11 April 2023, PT KAI, The Ministry of Transportation and DJKA operate free motorized transport trains (Motis) of passenger train type on the northern line (Cilegon-Semarang Tawang), central line (Pasar Senen-Purwosari), southern line (Kiaracondong-Purwosari Station) for the Motis train series (North, Central, South lines) carrying 4 economy cars (K3), 1 power dining car (KMP) plus 3 luggage cars (B).

Started on 2 April 2024, PT KAI, the Ministry of Transportation and DJKA are re-operating the free motorized passenger train (Motis) with the same route Cilegon-Semarang Tawang, but the Motis train for the central and southern routes in 2024 is now very different, namely the Pasar Senen-Kutoarjo route (shortened from the Purwosari route) and Pasar Senen-Madiun via Kiaracondong (extended from the Kiaracondong and Purwosari routes) (the previous route in 2023 was Pasar Senen-Purwosari and Kiaracondong-Purwosari).

Started on 20–29 December 2024, PT KAI, the Ministry of Transportation and DJKA are re-operating the free motorized passenger train (Motis) during the 2024 Christmas and 2025 New Year period, namely "MOTIS NATARU" with the route Pasar Senen–Lempuyangan and vice versa; previously the "MOTIS" service operated during the 2023 Christmas and 2024 New Year period, namely the Airlangga Motis.

On 1 January 2024 the South Parcel train from Surabaya Kota to Bandung suspended by KAI until an unspecified date. One year later, the South Parcel Train resumed operations on the same route starting 8 January 2025.

On 1 February 2025, the overnight service was schedule only at the over-night based from the enactment of new train travel chart 2025.

The train set for the operation of the ONS Parcel train uses baggage cars (B) made by PT INKA in 2007 to 2009. This baggage car is called the White Arrow with a green color scheme with a white arrow. In addition, it operates using a power-generating baggage car (BP) equipped with a crew room and a smaller power plant than the passenger car. In 2014, some of the used baggage cars were replaced with new ones from PT INKA with a green color scheme with the word "CARGO" written in large letters.
