The section between stations Luz and Guaianases was completely modernized in late '90s, when many stations parallel to Line 3 - Red were closed. Since then, this part of the Line 11 - Coral is also known as the East Express (Portuguese: Expresso Leste). After the modernized section was opened in May 2000 the line was divided into two sections, and passengers were required to switch trains to proceed. Since April 2019 the line is once again unified, but in rush hours additional trains might travel between Luz and Guaianases only in order to increase seat availability to the most demanding stations.[3][4]
As of April 2019, about 752,800 passengers use Line 11 - Coral each business day,[5] with a headway of 4 minutes during hush hours and 8 minutes off-peak.[6]

On Lines 1, 2 and 3, the track gauge is a non standard 1600 mm, the third rail is 750 V DC and under running. For Lines 4 and 5, the track gauge is 1435 mm and they use overhead pantograph, precluding any connection to the rest of the system, plus the 4 and 5 lines can't connect because the trains on the 4 line use drive-less technology while trains on 5 line are OPTO. Lines 7, 8, 9, 10, 11 and 12 (operated by CPTM) are all 1600 mm and use overhead pantograph.
