OMG...Finally got my question answered, I've spoken to a few T/Os, dispatchers and CIs at Westchester & Corona could not get a solid answer. Makes sense, I saw a 5 set at Broad Channel testing while I was in flag training about over 2 years ago then at Jay St (same set) with the plastic still on the seats heading north on the line. Just a few months ago I saw an R188 set in the Concourse Yard just sitting pretty waiting to be moved. Thanks for the info!
