NEW YORK - Transit advocates are planning to call on Governor Andrew Cuomo to do more to fix the subway and rail system's problems.

The Riders Alliance has organized a rally outside the Governor's Midtown office during the this evening's rush.

The group cites recent subway power outages as signs that the system is deteriorating.

They also say the governor needs to address dramatic increases in subway delays and overcrowding.

One power outage during the morning rush in April caused major service disruptions for several hours.

The Governor's Office says he has launched a state investigation into power problems on the subway.

It also slammed criticism from the Riders Alliance as "cheap and unconstructive".
