New York, NY - Atlantic Avenue Tunnel
The Atlantic Avenue Tunnel, as it is now called, was built in seven months in 1844 by the Long Island Rail Road [Map] to relieve congestion in downtown Brooklyn. In time, it became sort of an urban legend, and many stories were
born about it and what uses some people may be putting it to. There
were also various attempts to find it throughout the years. In the early
'80s, Bob Diamond heard about it, and became captivated. [Images
from Bob Diamond] He made it his mission to locate it, and through
several years of research and physical work, he entered the tunnel.
Occasional tours of the tunnel are given by Diamond.

Pontifex by Chronic Logic
Pontifex is the official sequel to a freeware game in which you design and test bridges. Pontifex uses a complex physics engine called the Immortal Engine which allows for many different types of bridges to be built. Once the design is completed you can test your bridge by sending a train across and watch as the train either passes over safely or plummets into the river below. The 3D engine lets you view your bridge from any angle including a first-person train view. Many different types of levels are included, from simple to complex, and a level editor lets you make your own levels to trade with other people.

Tunnel Design and Construction
Tunneling for transit projects is as much an art as a science. Variables affecting the design and construction of a project include predicting the behavior of ground mass during construction and the vagaries of ground-water hydrology. Predictive models are only of some use because no two projects are the same.
