The 5000 Series cars have been phased in since 2011, under decisions set in motion by Frank Kruesi, who was CTA president for 91/2 years during the administration of Mayor Richard M. Daley. The aisle-facing longitudinal scoop seats, which represent about 90 percent of the 38 seats in each 5000 Series car, broke the modern-day CTA tradition of having mostly forward- and- rear-facing seats. The strategy was to cram more riders onto each rail car, reduce the amount of time that trains are stopped at stations and operate more peak-hour train runs through the Loop "L" structure.
