About Highball
Highball shows you exactly when trains are arriving near you. Whether you're a railfan, a parent with a kid who loves trains, or just standing near the tracks wondering what's coming — Highball puts live train data in your pocket.
LIVE TRAIN TRACKING
See every train operating near you with real-time arrival countdowns. The hero timer shows the next train at a glance — no timetables to decode.
INTERACTIVE MAP
Watch trains move in real time with directional arrows showing which way they're heading. Tap any train for route details, speed, and ETA. When multiple trains overlap, swipe through the chip bar to select one.
SPOT LOG
Spot trains you see and build your collection. Every spot records the train number, route, time, and your location. Earn badges as you go — from Rookie to Train Master.
NOTIFICATIONS
Get alerted when a train is approaching within 15 minutes. Works even when the app is in the background so you never miss one.
SUPPORTED RAILROADS
• Metrolink (Southern California)
• Caltrain (San Francisco Bay Area)
• More agencies coming soon
FEATURES
• Live GTFS-RT data refreshed every 30 seconds
• Bearing inference shows train direction even when feeds don't provide it
• Pull-to-refresh on every screen
• Persistent spot log that survives app restarts
• English and Spanish localization
• Accessibility labels throughout
• No account required — just location
Highball is named after the historic railroad signal that meant "all clear — full speed ahead."
