I'm at Newark Penn waiting with my friend for his DC bound 159 NE Regional train. Due to track work, there is currently only one track open between NY and Newark Penn. Our NJ transit train had to wait at Secaucus for another train to pass. Once we got to NWK, a miniature pileup seemed to happen back at NYP. 163 from Boston was already an hour late, so they held 159 at NYP to let 163 pass. Meanwhile, a Keystone was held at NWK, to allow 163 to get out of NYP. That caused 159 to be even later. Update: It finally arrived at 1822, about an hour late.
