The paper reviews methods of engineering geophysics which can be applied to sections of railway tracks. The method of electrical resistivity tomography is used to study the properties of the geological situation under an engineering structure. In the course of practical work, two-dimensional geoelectric sections were obtained. Interpretation of the sections allowed to understand the structure of the near-surface zone.

Techniques of making seismic attenuation measurements are of interest in engineering geophysics because they allow rock type and quality to be estimated. The measurements may be made on field data from spectral amplitudes, amplitude decay curves, or observed pulse broadening. With shallow seismic refraction data, attenuation is best measured from the pulse broadening. I discuss the problem and demonstrate a computer technique for making routine measurements.
