After weeks of frustrating commutes, the LIRR rolled out more changes on Monday.

The changes came after rider complaints about crowded trains and missed connections.

Three peak trains now begin or end their trip at Penn Station instead of Grand Central. The rail road also changed where some trains stop to better balance riders between trains.

In addition, officials say they have added two or more cars to 30 of their most crowded rush hour trains.

For riders going to or from Brooklyn, the LIRR has increased rush hour service from every 12 minutes to every eight minutes. The LIRR says platform staff are now managing departures of these shuttle trains, so riders are more likely to make their transfers.
