could use mainly R46 and some R68/R68A borrowed but not sure because will also return to passenger service on Monday and using most of the Subway cars on Concourse and Coney Island Yards, could use some R46 and R160 they probably will use some R32.
may still have enough cars of R143 and R160 to use.
Like today was 100% R46 and used mostly R46 and a few R160 sets. uses less R46 sets and use more sets.
