Edinburgh has a really good bus system, I think. One of the many conveniences that it offers is real-time bus schedules. They are available on the Web, via an app, and on electronic display boards at the most important stops, mostly in the city centre. At many of the less crowded stops, however, there is no electronic display, and if you're not equipped with a smart phone you have to fall back to the printed schedule (which is available at most stops, mind you).
This little program
fills used to fill that gap by
providing live bus schedules over SMS. You send an SMS with the bus stop code
to a special number, and you should immediately get an SMS back with the
current live bus information for that stop.
(removed 2020-10-07 - the service has gone offline, so long and thanks for all the SMSes!)
The stop code is found at every stop. It is 8 digits long, and often starts with "36". For instance if you text "36236456" to that number, you'll get back something like this:
DUE 23-Trnt DUE 35-OcnTrmnl DUE 42-HnvrStrt DUE 47-PnckLwd 5 27-Slvrknws 11 47-PnckLwd 14 35-OcnTrmnl 16 2-GlCntr 21 47-PnckLwd 23 23-Trnt 24 2-GlCntr
The format should be roughly familiar, as it mimics the official bus tracker's: each line contains a forecast in minutes (or "DUE"), the line number, and the destination name. The vowels have been stripped out of the destination name to compress the output and make room for more data.
Built using the
excellent neat but frustratingly
unreliable Twilio API.
Fine print: whatever fees your phone company usually charges you to send and
receive texts still apply, of course, but this service will not otherwise
charge you. The catch is that it costs me about 3p per schedule lookup.
If this ever gets too expensive I'll just shut it down The
service is now offline, but its costs never rose to more than £1/month or
