The present Cascade Tunnel is 7.79 miles long. The original Cascade Tunnel was 2.63 miles long.
The Eisenhower Memorial Tunnel is 1.6 miles long...almost two miles long.
i think its about 4900 hours.im not good at math. Right on that! The train must travel 3 miles to go thru the tunnel and to the other end. Math is 20 miles in 60 mins......therfore 3 miles in 9 mins (60/20*3)
If you are timing from when the train first enters the tunnel until the last car exits the tunnel, then the train would travel 2 miles during this time.So 2 mi / (15 mi/hr) = (2/15) hr * 60 (min/hr) = 8 minutes
At 58 miles per hour it would take 17.63 seconds to travel 1,500 feet.
From the time the front of the locomotive enters the tunnel . . .-- The front of the locomotive traverses the 1-mile tunnel, bringing the center of the train to the entrance.-- The center of the train traverses the 1-mile tunnel, bringing the end of the train to the entrance.-- The end of the train traverses the 1-mile tunnel.In all, the train has to travel 3 miles. At the rate of 12 mph, it takes (3/12) = 1/4 hour = 15 minutes.
the answer is 14.5 miles
7.79 Miles
Cascade Tunnel was created in 1900.
The Eisenhower Memorial Tunnel is 1.6 miles long...almost two miles long.
Depending on the tunnel (there are three), they are 1.4 - 1.5 miles long.
The Hoosac Tunnel is 4.75 miles in length or 7.64 km long.
Mont Blanc Tunnel is 11.6 kilometres or 7.25 miles long
The Seikan Tunnel is 14.5 miles long, being one of the longest tunnels in the world.
the answer to this question would be about 140 miles long
It may be l4 miles. the Trans-Hudson ( Goddard) tunnel of the former PRR which will be l00 next year, is probably the longest subaqueous tunnel of it s type - and is rated for 80 MPH operation of heavy duty locomotives, not subway cars. The Goddard is l5,600 feet long or about 2.95 miles and some change- try it on a calculator. it has never been as much in the public eye as the automotive vehicular tunnels, the Holland and Lincoln.The Cascade tunnel ( which has an automatic ventilating system installed in the past 30-odd years with remotely controlled tunnel doors ( also keeping out vandals) and ventilation pumps turned on by approaching pressure waves of locomotives is a massive engineering feat, but is an intermountain ( name defines itself) tunnel and not a subaqueous ( Under water) type, the latter much more challenging to the engineer.
The Channel Tunnel is 23.5 miles (37.9 km) long.
It is 0.24 miles long, 1,262 feet long.
