Watch up to 4 cameras
Run multiple railfan cams side by side. Each gets its own worker, detector state, cooldown, and live frame, with no cross-talk.
Live train detection
Never miss a train again.
TrainWatch quietly watches public railfan webcams and pings your phone the instant a train rolls onto the tracks, using lightweight, local computer vision on low-res frames. No bloated models. No cloud bills. Just the alert.

The pipeline
Heavy AI is overkill.
Heavy AI is overkill.
This is just smart.
Most "AI camera" tools burn money streaming everything to the cloud. TrainWatch runs a deliberately cheap local detector on tiny frames, and only spends compute when something actually moves on the track.
- 01 low-res HLS
Sample cheap frames
TrainWatch grabs a single low-resolution frame from a public railfan stream every few seconds. No video decoding marathons, no GPU required.
- 02 local CV
Compare the track zone
It diffs your region of interest against a rolling background model. Wind in the trees and passing cars get ignored. Only sustained change on the rails counts.
- 03 direction + motion
Confirm the train
When change persists across consecutive frames above your threshold, it locks in a detection, then reads optical flow for direction and stopped/moving state.
- 04 Telegram now
Alert you, instantly
A Telegram message lands with the annotated frame, timestamp, direction, and motion state. One session per train, with no spammy duplicate pings.
All local: detection runs entirely on lightweight computer vision, with no cloud inference, no per-frame API bills, no surprise costs.
What's in the box
Built for the people actually trackside.
Every feature earns its place. No dashboards full of charts you'll never read, just the controls that make detection reliable.
Per-camera ROI tuning
Drag a region of interest right over the tracks, then dial in threshold, frames-in-a-row, and cooldown per view.
Direction + motion
Best-effort optical-flow reads northbound vs southbound and tells stopped trains apart from moving ones.
Telegram alerts
Confirmed trains push an annotated image, timestamp, direction, and motion state straight to your chat.
Live dashboard
Watch sample logs, candidate vs rejected events, confirmed findings, and the latest annotated frame in real time.
No duplicate spam
One active session per train keeps a stopped train from re-alerting every cooldown. You hear about it once.
