Color is not claimed as a feature of the mark.
The mark consists of a large, upper case "A" with railroad track coming from underneath it. A railroad crossing signal and gate are at the end of the company name, with the gate of the crossing lowered to underline the letters after the large, upper case "A". The gate crosses the "A" to completely make the letter "A". "Amtrac Railroad Contractors" is along the bottom of the logo.
The stippling is for shading purposes only.
