New Jersey and New York City commuters are facing extensive delays in and out of New York Penn Station Friday, with intensifying ripple effects, after an Amtrak work train car on one of the hub's tracks caught fire. The FDNY says it was called to the Midtown scene on 31st Street, between Seventh and Eighth avenues, around 1:30 a.m. Nearly 100 personnel responded. Five civilians were evaluated at the scene by EMS, officials say.
