How to use the online alarm clock
While you watch the clock for the appointed moment, set the alarm for 12:19 am so the relief crew can be released onto the railway tracks at the planned time. The late-night railway window may be narrow, and 1:00 am is still 41 minutes away, leaving enough time for the crew to prepare without sending them out early.
Before relying on the alert, make a quick test with a signal due in a minute or two and check that its volume is clear in the place where you are waiting. This confirms that browser sound is allowed and that the chosen alert can be heard above radios or nearby work. Keep the browser running and the computer awake: otherwise the alarm cannot sound, and the crew may miss its release time for the tracks.
Waiting beside a railway worksite after midnight can feel quiet until a train, vehicle or radio call suddenly masks a softer tone. Place the computer close enough to hear at 12:19 am, but away from paperwork and controls, and choose a distinct signal rather than one resembling site equipment. As activity fades towards 1:00 am, recheck the sound if the surrounding noise changes.
Common questions
Does the alarm still work if I close the tab?
No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
What happens if my laptop goes to sleep before 12:19 am?
The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
