NYC Subway: R211A F & "F Diamond" CBTC Test Train Action in Revenue Service (Spring 2026)

During May and June the R211A performed CBTC testing during regular service during Middays, nights and weekends as part of CBTC qualification testing on R211A base order trains to prepare them for the upcoming IND 8th Avenue Line CBTC. One trip was signed up as a "F Diamond" trip even though it was on a weekend due to it running behind schedule and being rerouted express from Jay St to Church Avenue. Enjoy!
