LFS artics displaced from SBS service. With the exception of 5364-5438, 6033-6081 (odd numbers only), 6101, 6105, and 6121, all of the blue-and-yellow articulated buses are for Select Bus Service...meaning one will ultimately have 416 LFS buses, 217 XD60s, and 93 XN60s for local service. Right now, the MTA is growing its articulated bus fleet with only rigids being retired.
