Here are several videos taken on April 16, 2021, featuring the MTA NYC Subway, in particular the Concourse Line! During the weekends of April 17 and April 24, 2021, D trains were cut back to Atlantic Ave/Barclays Center to allow for inspections on the Manhattan Bridge. As a result, the C, which uses some 8-car Bombardier Transportation R179 trains, was rerouted to Norwood/205th St to provide service on the Concourse Line during the daytime. During the nighttime, the rerouted C service was replaced with a shuttle D service to 145th St only (from Norwood/205th St), so any R179 train on the line was signed up as a D shuttle train.
The usage of R179 trains on the Concourse Line was halted a day later when it was found out that 8-car trains' stopping positions did not allow conductors to align correctly with conductor boards at several Concourse Line stations.
