The file name is GF EXP. (Output) Program computes from the centerline of survey (which may be any combination of straight lines and circular curves), the required offset to the outside and inside of curves (track alignment may be any combination of straight lines, parallel or at an angle to the centerline of survey, and circular curves and Crandall's transition curves); clearances required normal to the outside and inside of track; and angular corrections required when the columns are not radial to the centerline of track. These computations are done for each bent, (Input) required is basic track alignment and its relationship to the centerline of survey.
