[Updated 10/6 p.m. with FRA announcement]

The Federal Railroad Administration has released its official count of applications received for the second round of high-speed rail grants--that is, the corridor grants-- funded by the economic stimulus legislation, and the numbers are big.  FRA says it received 45 applications from 24 states, seeking a total of about $50 billion.

That's on top of the $7 billion states and localities requested in HSR round one, which focuses on individual projects. After those first-round applications came in, FRA said it planned to announce the winners of that round in October. But now after receiving the  round-two requests,  FRA Administrator Joseph Szabo said  that  the agency "will be announcing all awards this winter."

FRA has a total of $57 billion worth of applications but only $8 billion to spend on HSR under the American Recovery and Reinvestment Act.

Among the states seeking round two grants is New York, which is applying for $7.9 billion for a batch of improvements along the New York City-Buffalo corridor. Most of the funds would be for the Albany to Buffalo portion.

North Carolina Gov. Bev Perdue said Oct. 2 that her state has applied for more than $5 billion in high-speed rail grants. The funds would help finance improvements from Charlotte to the Virginia border on a corridor that would end in Washington. D,C,

Virginia is requesting $1.8 billion for 19 projects on the Petersburg-to-Washington stretch of that corridor.

California is seeking $4.7 billion, including $2.18 billion for projects on a planned Los Angeles-to-Anaheim segment; $980 million for a line from San Francisco to San Jose; $466 million for Merced to Fresno; and $819.5 million for Fresno to Bakersfield.

Florida is asking for $2.6 billion for its envisioned Tampa-Orlando line and $30 million for planning for an Orlando to Miami segment.

Pennsylvania weighed in with an application for $3.1 billion. That includes $2.3 billion to build the first phase of a magnetic levitation line in the Pittsburgh area. That "Phase A" would run from Pittsburgh International Airport to that city's downtown.
