Out of curiosity, will this approach Acela speeds? I'm sure someone here knows the stats.

I'm pretty sure Amtrak's NE Corridor will get some stimulus funds as well, which will make it even faster.
Today, the Acela averages 79.4 mph between NYC and D.C. (225 track miles/2 hours, 50 minutes), and 61.4 mph between NYC and Boston (215 miles/3 hours,30 minutes).
Although the Acela Express trainsets are capable of 200 miles per hour (320 km/h) operation, FRA regulations do not permit any speeds above 150 miles per hour (240 km/h) on tracks that are shared with freight and slower passenger trains regardless of circumstances; for Acela Express trains to run above 150 miles per hour (240 km/h), would require purpose built dedicated track in a separate right of way, similar to TGV networks under FRA regulations. Because of the mixed use nature of the NEC, there is no possibility for higher speeds than 150 miles per hour (240 km/h) under FRA regulations on the current NEC. Building a parallel right of way, dedicated to the Acela Express to the current NEC, is politically, socially, and financially unrealistic as of 2008.
To add, there's only two sections of tracks where Acela trains reach their maximum speeds of 150 mph in Rhode Island and Massachusetts, which total 18 miles. There are also many miles of track, especially east of New Haven, that have been upgraded to allow a maximum speed of 110 mph or 125 mph (177 km/h or 201 km/h). South of New York, Acela Express is limited to 135 mph (217 km/h), with many stretches of 125 mph (201 km/h) limits. Several stretches of track there are straight enough to allow 150 mph (241 km/h) speeds. However, the overhead catenary support system which was constructed during the Great Depression, lacks the constant-tension features of the new catenary east of New Haven, and cannot support running speeds over 135 mph (217 km/h).
On July 9, 2007 Amtrak introduced two limited-stop trains. Train 2105 left New York Penn Station at 6:50 AM, made only one stop in Philadelphia, and arrived in Washington at 9:25 AM. Northbound, train 2120 departed Washington at 3:55 PM, stopped in Philadelphia, and arrived in New York at 6:30 PM. This shortened the trip between the two cities to just 2 hours and 35 minutes.
Updating the NYC to D.C. to an average of 87 mph is appropriate.
Note, the Acela trains lose 8 mph average speed when stopping at more train stations. Upgrading catenary poles south of New York would allow 15 mph faster speeds on much of the existing tracks. So, there's plenty of upgrades Amtrak could make to make Acela trains faster, if they had the money.
