What is Caltrain Real-time and where tin can I find information technology?
Caltrain Real-time uses a combination of locomotive-equipped Global Positioning System and a runway operating command system to determine train location and departure prediction provided past the scheduled time. The prediction is available at the stations with visual messages, on Caltrain's website and on the 511 organisation (website, mobile, phone).
Is Caltrain Real-time actually "real-time"?
The term "real-time" describes the predictive time when Caltrain will depart, not get in, from a scheduled station. At the Caltrain stations, the organization provides status updates if a railroad train is predicted to depart more than than 2 minutes tardily from the scheduled fourth dimension. On the Caltrain website and 511 the system presents a countdown to the difference time.
What can I await from "real-time"?
At the station:
- Predictive departure times (next 2 trains inside the next 60 minutes)
- Display will show train number, schedule departure time, condition update compared to the scheduled fourth dimension
- "Minutes late" status update
- Audio announcements when train is budgeted or train lateness is greater than 5 minutes.
On caltrain.com:
- Predictive countdown to the next departure fourth dimension (adjacent 3 trains)
- Each station page volition display real-fourth dimension interface (car-refreshes every minute)
- Drib-downward station selection choice (does NOT auto-refresh)
- Mobile-friendly web interface selection

I receive this error message on the website: "An error occurred contacting the web service"
This error bulletin is displayed when no data is transferring through the spider web service. This is temporary and should come up back online.
I practice not run into any predictions on the website.
During a major service interruption, predictions are turned off when in manual mode . Once service is dorsum to normal, predictions will be reactivated.
Why practice some railroad train approaching announcements mention train numbers and others don't?
Due to the length of the display and sound message, only the train stopping at the station will accept the sound message proverb "Attention – railroad train XYZ approaching". Announcements without railroad train numbers refers to trains which are non scheduled to stop at the station ("Attending – railroad train budgeted"). While customers are at the stations, Caltrain strongly advises anybody to stand behind the yellow line at all times. Annotation: Non all the trains will be announced when approaching a station.
Why are there train numbers unlike from the scheduled timetable?
Caltrain offers additional service to adapt extra riders to local events. Most of the special service predictions also will be available on the Caltrain Real-time system. Trains with a published scheduled for an result volition start with "S" and the post-obit numbers will represent the railroad train direction (odd numbers are northbound and even numbers are southbound). In addition, trains adding extra capacity along the Caltrain corridor designated with "A" will normally run in advance of the regularly scheduled train (i.e. train A39 runs in advance of train 139)
Why practice some station displays say "arriving" and others say "departing"?
A railroad train departing its starting time scheduled station will display "departing" while along the line the displays volition testify "arriving".
What happens to the predictions at stations where the train may leave up to 5 minutes before (as noted in the timetable)?
The organisation will never predict trains departing early at the stations. Please refer to the timetable, if the railroad train, station and schedule is marked, brand certain to arrive at least 15 minutes prior to the railroad train departure time.
Tin can y'all turn off the sound announcements during sure hours of the 24-hour interval?
Caltrain keeps the train approaching announcements available at all times as a caution reminder to customers at the stations.
How come the "train delay" and "budgeted" audio and visual messages are sometimes tardily?
During the implementation and testing phase, the project team noticed the lateness of some of the announcements at the stations. Fifty-fifty though the Real-time predictions provided by the system at the stations, website and 511 are at 95 percent confidence level, we're investigating whether the delay may be caused by the aging communications infrastructure. Customers should always remain backside the xanthous safety line on the platforms.
* Stations without visual and audio messages are Capitol, Blossom Hill, Morgan Hill, San Martin and Gilroy. Stations without visual messages are 22nd Street, South San Francisco, Broadway, Atherton, Stanford Stadium and College Park.
