A method of efficiently delivering replacement railway ties for use in replacing ties that have deteriorated. GPS technology is used to obtain the GPS location of each tie that needs to be replaced. A tie train carrying replacement ties has a GPS monitor so that one or more ties can be unloaded at or near the location of each tie that requires replacement. A tie replacement crew can use a GPS monitor to locate each tie that requires replacement, and the crew can remove those ties and install a nearby replacement tie.

A method and apparatus for spreading ballast along railways makes use of an inertial measurement system to determine where to apply ballast from a hopper car. A variety of techniques can be used to determine the location and speed of the ballast spreading train, including manual or automated visual techniques, laser technology, radar technology, radio frequency transponders, magnetic sensor, thermal imaging and aerial photogrammetry. The invention also contemplates 'on the fly' surveys and terrain profiling using lasers or radar.
