XDs hold more people... the LFS doesn’t... Brooklyn depots wouldn’t be good for LFS because of that issue
Queens and Staten Island terrain wise are setup better for LFS... the Bronx can handle anything
Manhattan simply because it’s just too dense.. LFSA’s outside of Crosstown Routes don’t work
M15SBS is a prime example of why they don’t work... it’s killing the 1200s right now. XD60s would do the route much better in the long run
