The current contract between the Metropolitan Transportation Authority and the Transit Workers Union Local 100 expires at midnight, but union leaders will negotiate past the deadline with no threat of a transit strike.

Trains and buses will still run tomorrow morning, as TWU asks for salary increases from the cash-strapped MTA.

Newly installed MTA Chairman Joseph Lhota is hoping to get the union to agree to work rule changes in exchange for wage hikes.

TWU Local 100 represents 34,000 workers.
