FastTracks is a program intended to address the slow zones and to make train rides smoother and more reliable. In order to achieve this, crews would replace worn tracks, rail tires, and ballasts. An upgraded power system along the O'Hare Blue Line branch would enable more trains to operate during peak periods. The Blue, Brown, Green, and Red lines would be worked on. This program was set to begin in early 2018 and would continue through 2021. Funding for this $179 million project comes from a fee increase imposed on mobile app-based vehicle for hire companies in Chicago, the first of its kind in the country. In Mayor Emanuel's 2018 budget proposal, the fee went from 52 cents to 67 cents per trip. First introduced in 2015, this fee rose by another five cents in 2019.
