HST train free tickets already finished, the standard service already started end of last week. Tickets can be purchased using Whoosh website: https://ticket.kcic.co.id/webTrade/#/home/index or the specific app

There is still a promo active on Premium economy class (the basic class) at 150 K IDR until end of next week the the full fare to become 300 K IDR from Jakarta Halim to Padalarang or TegalLuar or vice versa. From to Bandung city is much better to go to Padalaranag stop and then transfer to the specific new shuttle train (called "feeder train") that links the HST line to the Bandung Kota station using the old line. Halim to Padalarang is 30 minutes and then Padalarang Bandung kota is 20 minutes, Tegal Luar station is far from the city, not well connected and the traffic from there is awful, to be chosen only if final destination is located in eastern part of Kabupaten Bandung.
