NEW YORK (CBSNewYork) — Starting Monday, the Long Island Rail Road is rolling out changes to its schedule and adding cars to some trains to help make the ride a little smoother.

Nine morning and evening rush hour trains will be adding one or two train cars to allow for more seating.

Because of the activation of a new modernized signal system, the rail road for the first ever is providing direct morning rush hour service from the Hamptons to Penn Station.

For the summer season, they’re also doubling weekend service to the North Fork of Long Island with four round trips between Ronkonkoma and Greenport.

But there will be some lines that will now see trains arriving later as crews work to test the positive train control system. PTC is an automated system that will slow a train down if it is speeding.

That testing will be done during off-peak hours during the day and overnight.

The LIRR is also launching “Summer Saturdays” beginning June 2nd. For 13 Saturdays, Monthly LIRR tickets will be honored system-wide to and from all 124 LIRR stations. Monthly pass holders can also bring up to four people with them for one dollar per person each way.

NYC Transit also announced it will provide additional service on several train and bus lines to help with demand. Starting in November, additional subway service will be added on the A, D, E, and F lines.

In July, additional weekend bus service will be added in Queens.
