NEWARK, N.J. (AP) - Talks between New Jersey Transit and rail worker unions are resuming in Newark to try and avoid a rail strike this weekend.

NEWARK, N.J. (AP) Talks between New Jersey Transit and rail worker unions are resuming in Newark to try and avoid a rail strike this weekend.

More than 4,000 NJ Transit rail workers have authorized a strike for early Sunday morning. The two sides have yet to agree on wage increases, health care costs and the length of a contract.

Unions have been working without a contract for nearly five years.

A NJ Transit negotiator said Thursday that although the sides aren't in agreement on the issues yet, he's optimistic because the tone of the meetings has been positive.

Gary Dellaverson (dell-AH'-ver-son) said the last two days have been marked by what he called "reasonable progress."
