The pause of MTA's congestion pricing plan could cost the transit agency $20 million.

MTA officials say they will now have to delay much-needed upgrades to aging LIRR cars. They say it is going to have to maintain older equipment now instead of replacing it.

The older train cars are a small part of the fleet on Long Island.

Riders will not have to deal with any costs from the congestion pricing pause, but they could have to deal with older cars that may not have air conditioning for longer.
