The American Society of Civil Engineers (or ASCE) specified rail profiles in 1893 [20] for 5 lb/yd (2.5 kg/m) increments from 40 to 100 lb/yd (19.8 to 49.6 kg/m). Height of rail equaled width of foot for each ASCE tee-rail weight; and the profiles specified fixed proportion of weight in head, web and foot of 42%, 21% and 37%, respectively.
These include simple rail adhesion, rack railways and cable inclines (including rail mounted water tanks to carry barges). To help with braking on the descent, a non-load-bearing "brake rail" located between the running rails can be used, similar to the rail used in the Fell system, e.g. by the Snaefell Mountain Railway on the Isle of Man.
The LTPP has been holding the LTPP data analysis contest in collaboration with the ASCE since 1998. The LTPP International Data Analysis Contest or the LTPP Data Analysis Contest is an annual international data analysis contest held by the American Society of Civil Engineers and Federal Highway Administration.
Rail profile – Looks for rail wear and deviations from standard profile. Warp – The maximum change in crosslevel over a predetermined chord length (generally sixty-two feet). [10] Track geometry cars used by the New York City Subway also measure: Corrugation of running rail surface; Tunnel and station platform clearances; Third rail height ...
For example, North America uses the reference rail as the line rail which is the east rail of tangent track running north and south, the north rail of tangent track running east and west, the outer rail (the rail that is further away from the center) on curves, or the outside rails in multiple track territory.

The reconvened ASCE met at the Chamber of Commerce of the State of New York until 1875 when the society moved to 4 East 23rd Street. The ASCE moved again in 1877 to 104 East 20th Street and in 1881 to 127 East 23rd Street. [10]: 2–3 [8] The ASCE commissioned a new headquarters at 220 West 57th Street in 1895.

The expeditions included surveyors, scientists, and artists and resulted in an immense body of data covering at least 400,000 square miles (1,000,000 km 2) on the American West. "These volumes... constitute probably the most important single contemporary source of knowledge on Western geography and history and their value is greatly enhanced by ...
