Inertial survey system, an advanced technology applied initially for conventional geodetic measurements, is now being used for developing railway engineering data. Mounted in a hi-rail vehicle, the inertial system involves an accelerometer coupled with a time measuring system to produce distance measures than can be converted in coordinate points. Track geometry and location of wayside structures can also be determined, the latter with a laser measuring device. Surveys on Chicago and North Western and in the Northeast Corridor are described. Inertial surveying can be done up to 20 times faster than conventional methods.
