You know the feeling: Standing at a stop some time in off-peak hours, maybe a Sunday morning, looking up Spruce Street or Baltimore Avenue or the El tracks – wondering when the bus, trolley or train will be arriving. You forgot to check the schedule and you’re late and getting later.

Well, SEPTA has unveiled a couple of new services that might ease your angst a little.

A new SMS service will allow you to punch a code for your stop into your phone, send a text to SEPTA and get the next four scheduled stops for your bus, trolley or train. Each of SEPTA’s 18,000 stops regionwide has a code. For now each code (called a “StopID”) is only available on SEPTA’s website here. This summer signs will be installed at all the stops with the unique code number.

The code is key. For example, the eastbound 34 trolley stop at 43rd and Baltimore has a number (it’s 20875). Send that number to 41411 and you will get a quick reply (it took eight seconds the first time we tried it) with the next four times a trolley is supposed to get to your stop. OK, supposed, is a key word here. There is no guarantee it will be on time. But, hey, they’re getting there.

If you like a little more precision, then look into another new service, TransitView, which is available for 116 bus routes and all of the trolleys (no trains) that service West Philly. For this one, you go to the interface and select your route. A Google map will pop up that will show you the location of all of the vehicles on that route by location. For example, on the map of the 34 (see image) the little red icon is a westbound trolley and the blue icon is eastbound. Using GPS updates, the locations are refreshed every three minutes.

There is a catch. The SMS services won’t work for T-Mobile or Sprint customers, which is a fairly big chunk of the Philadelphia market (about a quarter).

For those who can use them, the services will at least help you kill time while you wait.
