We present an atlas of the optical spectrum of the well known post-AGB star HD56126 associated with the IR-source IRAS 07134+1005, in comparison to a standard supergiant α Per. The high resolution spectra in the range from 401 to 879 nm were obtained with two Echelle spectrographs on the 6 m telescope. We have identified 1700 spectral lines, molecular features and diffuse interstellar bands (DIBs). Specific behavior of selected lines (Hα, Hβ and spectral features identified with FeII (42), C₂, CN, DIBs) is studied. The pattern of differential motions is revealed. Both the atlas and the table with line identification are available on the web at http://www.sao.ru/hq/ssl/Atlas/Atlas.html.
