SEPTA has spent $5.6 million installing cellular modems in its almost 1,400 buses and 159 trolleys. Similar equipment was installed on Regional Rail trains during the installation of Positive Train Control, an automatic-braking system. The modems will provide SEPTA, and riders, with location data on the vehicles that refresh every 30 seconds, much faster than the three-to-seven-minute updates currently available at train stations and on SEPTA's app. That more accurate information should start showing up at stations and on the app's schedules by the end of July. By the end of summer, maps on SEPTA's website and app, TrainView and TransitView, will receive information from the modems.
