From 1 October 2026, Argo Muria, Argo Sindoro, and Argo Merbabu to Use One Name: KA Muria

PT Kereta Api Indonesia (Persero) will simplify the identity of its train services on the Semarang Tawang–Gambir return route. Starting 1 October 2026, journeys previously operated under the names KA Argo Muria, KA Argo Sindoro, and KA Argo Merbabu will be presented under a single name, KA Muria.

Vice President Corporate Communication KAI Anne Purba said the naming simplification is intended to create a more concise, consistent, and easily recognisable service identity for customers.

“From 1 October 2026, customers will recognise journeys previously known as Argo Muria, Argo Sindoro, and Argo Merbabu under one identity, namely KA Muria. A simpler name is expected to be easier to remember when customers search for schedules or book tickets,” said Anne.

KA Muria will serve 12 journeys daily on the Semarang Tawang–Gambir return route, comprising six journeys from Semarang Tawang to Gambir and six journeys from Gambir to Semarang Tawang.

Departure options are available from morning to evening. From Semarang Tawang, KA Muria is scheduled to depart at 05.50, 07.00, 14.00, 16.55, 19.00, and 22.40 WIB. From Gambir, departures are available at 06.00, 07.15, 12.00, 16.45, 19.45, and 22.40 WIB.

With these schedule options, customers can continue to adjust their journeys between Jakarta and Semarang according to their individual activity needs.

“This identity simplification is being carried out in stages. We want KA Muria to become stronger as an easily recognisable name and to serve as KAI’s travel identity on the Semarang Tawang–Gambir route,” said Anne.

KAI urges customers who usually use KA Argo Muria, Argo Sindoro, or Argo Merbabu to take note of the KA Muria name when searching for schedules and making ticket bookings for journeys starting 1 October 2026.

Schedule information and ticket bookings can be accessed through the Access by KAI application and KAI’s official ticket sales channels.
