In addition to those that were rebuilt, new railroads developed after the Civil War.

Mr. Nelson said it was not certain how soon the railroad could develop the new passenger service, though it might be within 10 years.

Under Kidde's guidance, the railroad developed a plan to capture the market on travel to Midtown Manhattan.

The government and the railroads both shared in the increased value of the land grants, which the railroads developed.

Ms. Puglisi said the town and railroad would develop a survey to gauge commuter satisfaction with the station by next month.

"The railroads would have developed very differently and probably much slower without those land rights," said Eli M. Noam, a Columbia University economist.

Still, while the railroad was developing its infrastructure, canals continued to be expanded.

The railroad developed a spike in 1836 that soon became the standard for rails around the world.

Before the era of modern highways, many passenger and freight steamer routes linked the Chesapeake Bay region and connected with the railroads developed after 1830.

Somewhat later, steam power was mated with wheels needing to be steered, and railroads developed to become another type of internal improvement.
