alurail is an advanced real-time railway telemetry radar, rolling stock census database (locomotives, coaches, freight wagons), and curated railway photography platform in Indonesia built for transit observers, railfans, and the traveling public.
No. alurail is an independent, community-driven research platform. All timetable data is derived from official GAPEKA schedules and field telemetry observations, operating independently without corporate affiliation to PT Kereta Api Indonesia (Persero).
Core features include: Real-Time Live Train Radar, Comprehensive Rolling Stock Census Database, Station & Train Schedule Directory (GAPEKA), Daop/Divre Operational Boundary Maps, Curated High-Fidelity Railway Photography, Spotter Field Mode, and Onboard GPS Casting.
Yes, all primary features including live radar tracking, timetable lookups, fleet census archives, and station directories are freely accessible to the public without mandatory subscription fees.
alurail is accessible via modern desktop and mobile web browsers (alurail.web.id) as well as the native Android application (APK) optimized for low latency and efficient data consumption.
The alurail radar computes live train movements by harmonizing official GAPEKA timetables, sectional speed limits (TASPAT), OpenRailwayMap geodetic track vectors, Dead Reckoning/Viterbi route matching algorithms, and voluntary onboard GPS casting.
For trains with active onboard GPS transmission (Live Casting), positioning is accurate within meters. For timetable-interpolated trains, position reflects theoretical progress along the track based on scheduled station arrival and departure milestones.
Estimated positions are utilized when a train has no active onboard GPS telemetry stream. The system calculates continuous position along the track using the latest station departure time, sectional speed profiles, and scheduled arrival targets.
Telemetry packets are refreshed automatically every 5 to 10 seconds under standard connections, ensuring fluid icon interpolation while preserving client data bandwidth.
Yes, the alurail radar spans all active corridors across Java (Daop 1 - 9), Sumatra (Divre I - IV), the Jakarta-Bandung High-Speed Railway (Whoosh), and the South Sulawesi Pioneer Railway (Makassar–Parepare).
Markers differentiate service tiers: Blue for Commercial Intercity Trains, Orange/Yellow for Airport Express, Red for Commuter Line, Teal for LRT/MRT, Purple for Whoosh High-Speed Rail, Dark Slate for Freight, and Red/Green variants for Extraordinary/Inspection services.
Intercity trains operate long-distance cross-provincial services, Agglomeration trains connect regional urban economic clusters, and Local trains serve intermediate stops across smaller stations with public service obligation tariffs.
Commuters can filter map layers to Commuter Line or search by train code/line (e.g., CL Bogor, CL Cikarang, CL Tangerang, Airport Commuter) to see the live position of the EMU on the track.
Yes, operational alignments for LRT Jabodebek (Dukuh Atas - Harjamukti / Jatimulya), South Sumatra LRT (Palembang), and Jakarta MRT (Lebak Bulus - Bundaran HI) are fully integrated with stations and real-time markers.
Whoosh High-Speed trains are visualized traversing the standard-gauge (1,435 mm) dedicated alignment between Halim, Karawang, Padalarang, and Tegalluar Summarecon stations with velocity indicators up to 350 km/h.
alurail tracks strategic national rail freight, including Intermodal Container Trains, Bulk Cement, Fuel Tankers (Pertamina), Long-Consist Coal Trains (Babaranjang/Baratarahan in Sumatra), Crude Palm Oil (CPO), and Overnight Parcel Express services.
A KLB (Kereta Luar Biasa) represents a non-timetabled special movement scheduled outside regular GAPEKA operations, such as newly commissioned rolling stock delivery, track inspection runs, government VVIP specials, or maintenance movements.
Consist Transfer moves passenger cars between depots, Test Runs validate mechanical performance following Balai Yasa overhauls, and Light Engine movements reposition solo or multi-unit locomotives without rolling stock.
KAIS trains are dedicated track infrastructure safety inspection units; Rail Clinic provides mobile healthcare and clinics for remote communities; and Rail Library serves as a travelling educational library across the network.
Yes, heavy track maintenance units such as Plasser & Theurer machines (Multi-Tie Tamper, Ballast Regulators, Track Stabilizers) feature designated markers when deployed on active maintenance work.
The Fleet Census Database is a comprehensive digital registry indexing individual road numbers, builder serials, manufacturing years, operational status, and home depot assignments for all locomotives and cars in Indonesia.
Profiles include Ministry of Transportation registration codes, legacy road numbers, prime mover diesel specifications (GE/EMD/Krupp), horsepower output, wheel arrangement (Co-Co, Bo-Bo), weight in working order, max speed, and home depot allocation.
Listings cover classic diesel-hydraulics (BB 200, BB 300, BB 301, BB 304), mainline workhorses (CC 201, CC 203, CC 204), heavy-haul dual-cabs (CC 206), high-power coal haulers (CC 205), as well as electric high-speed trainsets (CR400AF) and EMUs.
Yes, the census catalogs the newest passenger stock built by PT INKA, including Stainless Steel New Generation Executive and Economy coaches, Luxury Sleepers, Panoramic coaches, and Suite Class Compartment cars.
Each vehicle card displays a verified operational badge: 'Active Service (SO)', 'Scheduled Maintenance (PB)', 'Periodic Inspection', 'Temporarily Stored/Conserved (TSO)', or 'Retired/Preserved for Heritage'.
alurail supports all 9 Operational Regions in Java (Daop 1 Jakarta through Daop 9 Jember) and 4 Regional Divisions in Sumatra (Divre I Medan, Divre II Padang, Divre III Palembang, and Divre IV Tanjungkarang).
Open the Map Settings panel or Layering menu and toggle 'Daop/Divre Boundaries'. The territorial jurisdiction polygons will overlay seamlessly on the map canvas.
Station pages show official telegraph codes, elevation above sea level (masl), station classification, track layout counts, passenger amenities, historical background, and live arrival/departure boards.
Yes, major facilities like Balai Yasa Manggarai, Balai Yasa Yogyakarta, Balai Yasa Gubeng, Balai Yasa Lahat, and principal locomotive depots (e.g., JNG, SMC, BD, YK, SDT) are marked with distinct icons.
By activating the railway infrastructure overlay, users can explore historical heritage alignments, abandoned colonial-era branch tracks, and industrial spurs connecting ports and industrial facilities.
alurail operates on the latest official GAPEKA 2025 timetable database authorized by the Directorate General of Railways (DJKA) and PT Kereta Api Indonesia (Persero).
Type the station name or 3-letter telegraph code (e.g., 'Gambir' or 'GMR') into the universal search bar, then click the station result to display its full timetable board with train numbers and scheduled times.
A consist diagram visualizes the exact vehicle makeup of a trainset (e.g., Locomotive + Power Generator + Executive 1-4 + Dining Car + Economy 1-4). Users can view it by clicking any train on the radar or in the directory.
Yes, the system continuously compares the latest station checkpoint timestamps and live GPS telemetry against the GAPEKA timetable to calculate real-time schedule deviations (on-time / delayed in minutes).
Real-world rail operations such as unscheduled train meets on single tracks, platform congestion at terminal stations, temporary speed restrictions for track repairs, or inclement weather can cause variances from published schedules.
Spotter Mode is a specialized interface for railway photographers and trackside observers, offering an uncluttered radar HUD, upcoming train approach alerts for your vantage point, travel vectors, and active locomotive road numbers.
Launch alurail while riding a train, select your train service, and tap 'Start Live Casting'. Your device's GPS telemetry will then transmit coordinates to update the train's marker position in real time for the entire community.
Completely secure. GPS coordinates are snapped directly to the railway track geometry to advance the train position. No personal identity, contact details, or device identifiers are broadcast or shared publicly.
