Abstract:

A computer program was developed to assist the determination of minimum tunnel diameters for electrified rapid transit systems. Inputs include vehicle shape, walkway location, clearances, and track geometrics. The program written in FORTRAN IV calculates the locations of six critical points with respect to the top of the low rail. Twenty triplets of points are considered, each triplet defining a possible circle. Circles not containing all six points are discarded and the minimum-diameter circle is selected. An additional plotting option is available to provide a visual presentation of tunnel, vehicle envelope, and walkway envelope
