Project Excelsior was a series of parachute jumps made by Joseph Kittinger of the United States Air Force in 1959 and 1960 from helium balloons in the stratosphere.
 The purpose was to test the Beaupre multi-stage parachute system intended to be used by pilots ejecting from high altitude.
 In one of these jumps Kittinger set world records for the highest parachute jump, the longest parachute drogue fall and the fastest speed by a human through the atmosphere.
 The record for fastest speed by a human through the atmosphere is now held by Felix Baumgartner of the Red Bull Stratos project.
William Clyde "Bill" Elliott (born October 8, 1955), also known as Wild Bill, Awesome Bill from Dawsonville, or Million Dollar Bill, is a retired NASCAR driver.
 He won the 1988 Winston Cup Championship and has garnered 44 wins in that series, including two Daytona 500 victories in 1985 and 1987 and a record four consecutive wins at Michigan International Speedway between 1985 and 1986.
 He holds the track record for fastest qualifying speed at Talladega at 212.809 mph and Daytona International Speedway at 210.364 mph , both of which were set in 1987; the mark at Talladega has since been the fastest speed for any NASCAR race ever.
The Acela Express ( ; colloquially abbreviated to Acela) is Amtrak's flagship service along the Northeast Corridor (NEC) in the Northeast United States between Washington, D.C. and Boston via 14 intermediate stops including Baltimore, Philadelphia, and New York City.
 The route contains segments of high-speed rail, and Acela Express trains are the fastest trainsets in the Americas; they attain 150 mph on 28 mile of the route.
Thruway Motorcoach is Amtrak's system of Amtrak-owned intercity coaches, locally contracted transit buses, through-ticketed local bus routes, and taxi services to connect Amtrak train stations to areas not served by its railroads. Train and Thruway Motorcoach tickets are purchased together from Amtrak for the length of a passenger's journey, and the connections are timed for convenient dedicated and guaranteed-reliable transfers between the two services.
 In addition to providing connecting service to unserved areas, some Thruway Motorcoaches operate as redundant service along well-established passenger rail corridors to add extra capacity.
This is a list of the fastest flying birds in the world.
 A bird's velocity is necessarily variable; a hunting bird will reach much greater speeds while diving to catch prey than when gliding.
 The bird with the greatest airspeed velocity is the Peregrine falcon, able to exceed 320 km/h (200 mph) in its hunting dives.
 The greatest self-powered horizontal speed is achieved by Homing Racing Pigeons.
 They can fly 1100 km (700 miles) in a single day, and they have been recorded flying at 177 km/h (110 miles per hour) making them the fastest flying birds with the fastest speed ever recorded on a self-powered flight, and the fastest longest endurance flight.
The 1987 Maryland train collision occurred at 1:30 pm on January 4, 1987, on Amtrak's Northeast Corridor main line in the Chase community in eastern Baltimore County, Maryland, United States, at Gunpowder Interlocking, about 18 mi northeast of Baltimore.
 Amtrak train 94, the "Colonial" (now part of the "Northeast Regional", from Washington, D.C., to Boston), crashed into a set of Conrail locomotives running light, and which had fouled the mainline.
 Train 94's speed at the time of the collision was estimated at about 108 mph .
 Fourteen passengers on the Amtrak train were killed, as well as the Amtrak engineer and lounge car attendant.
The motorcycle land-speed record is the fastest speed achieved by a motorcycle on land.
 It is standardized as the speed over a course of fixed length, averaged over two runs in opposite directions.
 These are special or modified motorcycles, distinct from the fastest production motorcycles.
Westbrook is a regional rail station on the Northeast Corridor, located off Connecticut Route 153 just north of the village center of Westbrook, Connecticut.
 It is served by the Connecticut Department of Transportation's Shore Line East commuter rail service; Amtrak's "Acela Express" and "Northeast Regional" services run through the station without stopping.
The Northeast Regional is a higher-speed rail service operated by Amtrak in the Northeastern and Mid-Atlantic United States.
 In the past it has been known as the "NortheastDirect", "Acela Regional", or "Regional".
 It is the busiest Amtrak route, carrying 8.04 million passengers in fiscal year (FY) 2013, a 0.4% increase over the 8.01 million passengers in FY2012.
 The "Northeast Regional" service earned over $568.7 million in gross ticket revenue in FY2013, a 6.2% increase over the $536 million earned during FY2012.
Overspeed is a condition in which an engine is allowed or forced to turn beyond its design limit.
 The consequences of running an engine too fast vary by engine type and model and depend upon several factors, chief amongst them the duration of the overspeed and by the speed attained.
 With some engines even a momentary overspeed can result in greatly reduced engine life or even catastrophic failure.
 The speed of an engine is ordinarily measured in revolutions per minute (RPM).

Question: What is the fastest speed attained by Amtrak's one of the two services (the other being "Northeast Regional") that serve Westbrook?
Answer: 150 mph
