Live speed
Read the current speed in km/h, mph, or m/s and switch units without restarting.
Train Speed Test
Check a train's live speed from your phone's GPS. See current, maximum and average speed, distance, elapsed time, direction and GPS accuracy in km/h, mph or m/s.

DIRECT ANSWER
How can I check train speed on my phone?
Open this page on a GPS-capable phone, tap Start speed test, and allow location access. The browser reads successive positions and, when available, the device's own speed value. No route is sent to BanglaTools.
speed = distance travelled ÷ elapsed timeA COMPLETE TRIP READING
More than one changing number.
The main display stays easy to read on a moving train, while the trip panel keeps the context needed to judge the signal and journey.
Maximum and average
Compare the fastest reading with a trip average based on measured distance and active time.
Distance and direction
Follow the estimated distance, elapsed time and GPS heading during the test.
Signal context
See the reported GPS accuracy and last update time instead of assuming every reading is exact.
BETTER GPS RESULTS
Give the phone a clear view of the sky.
GPS quality changes during a journey. These small choices usually produce a steadier reading.
Move near a window
Metal carriages, coated glass and the centre of a coach can weaken satellite signals.
Wait after tapping Start
The first fix may be rough. Watch the accuracy value for a few seconds before judging speed.
Expect gaps in tunnels
Speed may freeze or drop when the phone cannot receive a usable position.
Keep the page visible
Some phones reduce location updates when the browser is locked or placed in the background.
USE IT FOR CURIOSITY
This is not a railway instrument.
Phone GPS readings can lag, jump or disappear. Do not use this page for railway operations, track safety, speed-limit decisions, or any situation where an official instrument is required. Keep your phone secure and do not lean outside a window.
KEEP IN MIND
What changes the reading
Phone and browser
GPS hardware, battery-saving settings and browser update frequency differ between devices.
Coach and surroundings
Tunnels, stations, dense buildings, mountains and carriage materials can obstruct signals.
GPS accuracy
The displayed accuracy is an estimated radius, not a guarantee that the speed is exact to that amount.

COMMON QUESTIONS
Train speed test: common questions
Quick answers about mobile GPS, units, accuracy, privacy and use on Bangladesh trains.
Can I check train speed online without an app?
Yes. A current mobile browser can request GPS location directly after you tap Start. You do not need to install an app or create an account.
Why does the speed stay at zero?
The phone may still be waiting for a GPS fix, location permission may be off, or the train may be in a tunnel or station. Move near a window, keep the page open, and check the accuracy value.
How accurate is a phone GPS speed test?
It varies by phone, signal and surroundings. Open sky and steady movement are usually better than tunnels or dense stations. Use the displayed accuracy and last update as context, not as a guarantee.
Does BanglaTools save my train route?
No. Position, distance and speed are processed in your browser. The page does not upload or store your route.
Can I use mph or metres per second?
Yes. Switch between km/h, mph and m/s at any time. The trip continues while only the displayed unit changes.
Will the test work on a laptop?
It can work if the device and browser provide a changing location, but phones with GPS usually give a more useful live result. Desktop location may be approximate or stationary.
